+ better rand() from Knuth's TAOCP (Luc Van Oostenryck)
+ fix unified x86_64 unified syscall 64-bit return value issue (Gwenole)
+ the getdents64 emulation was broken and repairing it opened a can of
+ worms. So I ripped it out. I also changed the readdir64 emulation
+ to work if there is no getdents64.
+ fix ia64 start.S (Thanks to Volker Birk for an account on his ia64 box)
+ many ia64 fixes (waitpid, nice, fork, vfork, time, utime ...)
+ More fixes from Gwenole (printf %p only printed the last 32 bits, I
+ botched the getdents64 #ifdefs, we violated the x86_64 ABI)
+ change signal() to do as glibc does
+ remove a few more warnings
+ add new 2.5 syscall #defines
+ add epoll_create, epoll_ctl and epoll_wait
+ the new x86 syscall numbers exceed 255, breaking our %al optimization
+ I worked around it with conditional assembly in cpp macros. Ugh.
+
+0.21:
+ use gcc's size_t, ptrdiff_t and wchar_t types (Olaf)
+ use -G 8 on MIPS to reduce code size (Johannes Stezenbach)
+ add munlock (Jens Låås)
+ argh, atexit fell victim to bit rot (or maybe Olaf)
+ add WANT_INET_ADDR_DNS to make gethostbyname not look up IP numbers
+ but use them to fill in the struct hostent directly.
+ signal is now a correct signal (Olaf)
+ read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
+ the built-in defaults.
+ add file "SECURITY". I will document design tradeoffs that have
+ security implications there.
+ fixed regex LINEEND condition
+ add .size directive to i386 syscalls
+ shove a few more bytes off the i386 socket calls

+0.19:
+ current gcc cvs makes __thread a keyword (Eric Troan)

+ add libm2.s from contrib to i386 (oops, how long has it been sitting
+ there?)
+ add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
+ Michal Ludvig ported the diet libc to the x86_64 architecture (the
+ upcoming AMD Hammer chips!). You can't even buy the chips yet and
+ the diet libc already supports it! Amazing ;-)
+ Michal's patch also fixed several of the outstanding warnings. Thanks!
+ Andre sent a patch to add ARM profiling. He says it does not work
+ yet, but it's a start.
+ added getdents64 backwards compatibility and include it in large file
+ support #defines
+ perror now checks if the message is NULL like glibc (Thomas Ogrisegg)
+ ftell did not take ungetc into account (Kevin Ryde through Debian).
+ Thomas Ogrisegg sent a port to IA64!

+
+0.17:
+ fix several bugs in getservent_r
+ Gunnar Ritter reported the following:
+ moved tcgetpgrp and tcsetpgrp to unistd.h
+ adjusted lstat->lstat64 #define to make it work with function pointers
+ move __dietlibc__ #define from features.h to diet
+ Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
+ an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
+ Thomas also sent me profiling support (so far only on x86, but
+ profiling/PORTING describes what needs to be done for other
+ architectures)!
+ add contrib/dprof.c, also from Thomas.
+ Andreas Krennmair sent a patch to add the BSD regex interface to
+ libcompat
+ Andre noticed that __dtostr never sets first to false. Oops!
+ Andre has provided a largely untested patch that seems to fix the problem.
+ Igor Gilitschenski sent a patch for the "%8.7lx" issue.
+ abort did not flush all stdio streams
+ fix some nasty regular expression bugs
+ write a stupid malloc checker (contrib/debug-realloc.c) to help me
+ debug my regular expressions. Please read contrib/debug-realloc.txt
+ our i386 memchr,memcmp were broken for the count=0 case
+ fix DNS domain search
+ i386 memccpy exchanged esi and edi :-( I should do more checks before
+ accepting external code...
+
+0.16:
+ "diet -v" or "diet -Os" segfaulted without further arguments.
+ Andre found two very embarassing bugs in my four lines of md5 glue.
+ I need to get more sleep.
+ Thanks Ogrisegg found that ptrace does not work as documented and
+ provided a wrapper that emulates the glibc behaviour.
+ Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
+ fix ptrace.h for S/390 and ARM
+ provide a PORTING document so we don't lose track of which file need
+ to be touched to port the diet libc to a new platform.
+ remove a few warnings
+ provide a prototype for usleep.
+ make __dtostr work on ARM by using long instead of long long.
+ Idea by Dirk Engling.
+ fix an argument counting bug in *scanf (Thomas Ogrisegg)
+ Forgot an #endif in asm/sigcontext.h (Mike Castle)
+ Kurt Garloff sent in patches to
+ fix struct termios on non-x86 architectures
+ printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
+ create libcompat.a (and move daemon to it)
+ add getdelim and getline
+ *printf now recognize 'z' integer flag (and ignore it)
+ Dirk Engling provided a strcpy.S for ARM.
+ Olaf: fixed *scanf familie. It hadn't wored with "long long".
+ Hans Lermen fixed i386/getenv.S
+ diet -Os no longer discards -fpic and -fno-pic
+ fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
+ Macodiseas)
+ sys/ipc.h now includes sys/types.h
+ Olaf: started to make the sparc64 port
+ scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
+
+0.15:
+ vfork sucks. I reverted to the old behavior where vfork==fork.
+ fix bsearch (and remove i386 assembly bsearch, needs to be redone).
+ Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
+ thread-safe!
+ remove vfork and add alarm to dynamic syscalls.
+ fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
+ The MD5 code generated unaligned accesses when passed an unaligned
+ pointer on little endian ARM and MIPS.
+ MIPS unified syscall didn't compile anymore.
+ Put up new mipsel target to cross compile for little endian mips.
+ The mips target will again explicitly set endianness to big endian.
+ Compiling natively on a MIPS box should not touch the endianness.
+ Duh, when we removed return0, we broke tzset when the time zone parser
+ was disabled. Uwe Ohse noticed this. Thanks!
+ Fix gethostbyname to match host names case insensitively in /etc/hosts.
+ Oops, this was reported 6 weeks ago but I overlooked the email.
+ Thanks, Denis Rachal!
+ vsnprintf's zero termination was broken.
+ Uwe Ohse found a few more bugs:
+ Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
+ does it correctly.
+ Make inet_aton use strtoul instead of strtol
+ fdopen would close the file descriptor if it could not malloc the
+ buffer.
+ strftime updates.
+ Make _FILE_OFFSET_BITS includes -Wundef clean
+ Andre found a typo in endian.h for big endian mips
+ Ryan told me that fmod was not included in libm. Oops.
+ strstr(whatever,"") returned NULL, not whatever. Found by a new test
+ suite entry for strstr that I wrote.
+ Thomas Ogrisegg suggested or sent patches for the following:
+ add <asm/sigcontext.h> for profiling support.
+ make strncpy a #define in string.h to save a few bytes.
+ an i386 assembler getenv implementation (roughly half the size)
+ add grantpt, ptsname, unlockpt
+ add a getenv test suite entry.
+ Andre contributed an ARM assembler md5 implementation and he fixed mmap
+ on ARM.
+ add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
+ getservent_r did not parse lines without aliases. Thanks, Jaroslav
+ Macodiseas!
+ fix MIPS start code (argv[0] was always corrupt)
+ removed annoying -Wconversion gcc switch
+ add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
+ Kurt Garloff sent these diffs:
+ add fdatasync (and make it a pthread cancellation point)
+ numerous alpha issues, like using .quad instead of .long for
+ offsets, change strip to -strip in Makefile (so a failing strip does
+ not abort the make), try to be more friendly to the gcc 2.96 that
+ SuSE 7.1 AXP ships with.
+
+0.14:
+ fix brk again (missing __brk, trivial oversight)
+ a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
+ Thomas Ogrisegg!
+ Thomas also contributed a PA-RISC port including testandset, so
+ libpthread will work once we implement clone! Great work, Thomas.
+ made the fake locale more believable.
+ If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
+ moved _exit into the unified syscall on x86.
+ Uwe Ohse found many more bugs:
+ getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
+ liblatin1 was more or less completely broken if you gave it chars as
+ arguments, not ints (signedness). execvp had a buffer overflow in
+ case a PATH element exceeded PATH_MAX, but it's not a security
+ problem since setuid programs need to set their path to some known
+ value anyway.
+ hasmntopt did not work with foo=bar style options
+ Uwe also improved ftw's stack usage.
+ Put movl instead of popl rationale in comment in i386/unified.S since
+ three people have suggested saving a few bytes with popl now ;)
+ I discovered __attribute__((malloc)) and started using it. For gcc 3,
+ it improves the optimizer when functions return malloced pointers.
+ Steven Rostedt pointed out that my setvbuf was broken with regard to
+ size==0 and sent a patch to fix it.
+ Thomas Ogrisegg made setenv smaller.
+ Olaf: implemented the parisc clone and an atomic testandset, modified the
+ libpthread to respect the parisc UPgrowing stack. still non functional,
+ because the unified syscall uses errno :(
+ tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
+ Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
+ don't write anything which was no longer the case. It also
+ allocated one byte unnecessarily, which Uwe Ohse found.
+ Fix ttyname (readlink does not \0-terminate, forgot to do that).
+
+0.13:
+ add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
+ make diet not include the linker safeguard stuff when preprocessing
+ Olaf: port to S/390!
+ me: fix vfork (it was put into dietlibc.a twice)
+ res_query did not initialize last
+ diet (not diet-dyn, of course) now adds -static to the gcc command line
+ fixed fflush on input streams (tic from ncurses exposed this)
+ duh, there is an alarm system call, too, so we use it and not setitimer
+ fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
+ rewrote __dtostr (it also has one more argument now)
+ Thanks to Erik Troan for bringing these to my attention:
+ make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
+ fix strncat for the case where n == 0 (security implications?)
+ fix bsearch (it didn't find the very last element in the array, same
+ bug in both the C and the i386 assembly version).
+ fixed FNM_PATHNAME in fnmatch
+ fix brk (the syscall was documented incorrectly in the Linux man page)
+ Thanks, Thomas Ogrisegg!
+ added negated character classes to fnmatch (not required by POSIX)
+ make the utmp routines open utmp read-only if read-write doesn't work.
+ remove syscalls.c directory, it is obsolete now with unified syscalls
+
+0.12:
+ more contributions from Frank Klemm.
+ iconv can now do UCS-2, too.
+ Imported several x86 assembly routines from Wouter van Kleunen.
+ Lots of bug fixes, and several more i386 specific versions of common
+ routines to make them smaller.
+ add memmem (a GNU extension that looks useful)
+ several changes from Michal Ludvig: inttypes.h gets C99 macros,
+ add pivot_root syscall, %n for *scanf.
+ add adjtimex (thanks, Laurent BERCOT)
+ add Frank Klemm's optimized md5
+ add -Os option to diet (see diet.1).
+ several IPv6 constants and HZ were missing, thanks Johannes Kloos.
+ add 32-bit uid/gid syscalls.
+ add rand48 (thanks, Johannes Kloos)
+ fixed a lot of bugs in getopt* (thanks, Johannes)
+ add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
+ add a few more module syscalls. modutils-2.4.9 now compiles without changes.
+ fix gethostent alias list termination. Major oops.
+ add execle and two DNS constants (from Johannes Kloos).
+ opendir did not close-on-exec (thanks, Laurent Bercot).
+ DNS will now properly signal errors and set h_errno.
+ A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
+ Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
+ If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
+ external reference to a symbol that is only in the diet libc. So,
+ when you accidentally link a diet libc compiled object file against
+ glibc, the linker will barf. This will bloat your object files, but
+ you can remove all the references with "strip -R .note" from
+ the binaries in the end (which you should do anyway).
+ fix ARM unified syscall (select did not work).
+ add getpwent_r ala glibc and replace getpwent
+ do the same for getgrent and getspent
+ remove entlib (new code is smaller)
+ rewrite getserv* to use parselib (and provide ..._r, too)
+ add getpwnam_r and getpwuid_r
+ rewrite getproto* to use parselib (and protive ..._r, too)
+ Olaf muddled with the dynamic linker. It's a clean-room
+ implementation in the sense that it once worked for Olaf in a clean
+ room ;)
+ add if_nameindex and if_freenameindex.
+ fixed arm unified syscalls to work with current binutils (; is no
+ longer a line separator but starts a comment, switched to .macro)
+ changed all st_[cma]time types to signed long so comparisons against
+ LONG_MIN will work correctly. (GNU tar does this)
+ fixed two bugs regarding ungetc.
+ add getusershell, setusershell, endusershell (for vs_ftpd)
+ add prctl, dirfd (also for vs_ftpd)
+ fixed strftime (was completely hosed)
+ added real make install target
+
+0.11:
+ fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
+ fix vsscanf bug (Thanks, David Chappell).
+ add floor, ceil and memchr prototypes.
+ add __builtin_expect and expect #defines for gcc versions below 3.0
+ cleaner errno vs __errno_location handling
+ add placeholder iconv (iconv_open will always return EINVAL)
+ try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
+ initialization of getaddrinfo.
+ fix vsnprintf %X (printed lower case)
+ I wrote a new getopt. It appears to actually work (it is POSIX
+ compliant, it does not sort argv like the GNU version) and is only
+ a little over 300 bytes on x86.
+ Guillaume Cottenceau just wrote me that strncat should be even more
+ broken than it already is: it should append n bytes AND THEN \0!
+ I wonder how many programmers have produces off-by-one errors here...
+ Fix regexec offset return. autoconf now believes that diet libc has
+ POSIX regular expressions.
+ Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
+ Fix regular expression match for x* when there is no x at all.
+ Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
+ Add %h to vsnprintf.
+ Add FAQ.
+ Make %h work for signed numbers and add %hh to vsnprintf.
+ initgroups ignored the group argument :-(
+ remove printf references and nested functions from glob.
+ added an errno in libpthread that will display a prominent linker
+ warning.
+ started getting rid of kernel headers. Big task! :-(
+ add res_mkquery. The diet libc can now compile and link mtr.
+ Olaf: added a lot of code in libdl (not yet complete), changed the
+ startup code to make it work with his libdl and ld.so (needs still work
+ too)
+ __dns_readstartfiles only took the first domain or search path.
+ Thanks, Anthony de Boer
+ Olaf: added clone and a new unified_syscall for PowerPC
+ also dynlinker is now available (i386 only at this time)
+ crufted together a stdarg.h implementation from the various gcc headers.
+ implement getopt_long (ugh, the GNU people need professional help)
+ fixed word delimiters in regex (they looked for space, i.e. "," did
+ not work as delimiter)
+ errno.h now declares sys_errlist and sys_nerr.
+ added mkdtemp.
+ Uwe Ohse reported all of the following bugs:
+ ttyname should return 0 if !isatty.
+ realpath returns NULL if "." cannot be opened
+ putenv erroneously accepted (and mishandled) entries without "=".
+ popen returned 255 instead of 127 if /bin/sh could not be run.
+ fgetc did not set the internal EOF indicator on EOF.
+ bsearch contained an assumption about integer arithmetic overflow
+ behavior.
+ system did not set SIGCHLD and thus contained a race.
+ popen did not set close-on-exec and could leak an fd on malloc error.
+ daemon did not check whether open returns an fd below 3
+ perror did not save errno.
+ Olaf: Peter Jones reported some problems with perror; strerror had the
+ same problem.
+ Peter also posted a patch to atexit/exit. With some modifications it is
+ now implemented.
+ Unbuffered stdio and ungetc can no longer be disabled. I will try to
+ implement part of it using ELF weak symbols.
+ Added minimal sysconf (tehe) from David Chappell.
+ Added overflow handling for strtoul and strtol.
+ Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
+ it before falling back to DNS if enabled.
+ Added a littie backwards compatibility cruft for gpm (man, do these
+ sources stink!)
+ Added openpty.
+ Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
+ Fix fseek return value.
+ Add dirname and basename.
+ Add a few i386 math routines contributed by Frank Klemm.
+ Fixed getservent (did not allow _ and - in the aliases).
+ Thanks, Oden Eriksson
+ Added a float.h so configure believes we have ANSI header files.
+ Fix a lot more stdio bugs that Uwe Ohse pointed out.
+ Olaf: has added a new scanf and printf core that is suitable for all
+ scanf and printf function implementations
+ Imported a few more functions and optimizations from Frank Klemm (he
+ also rewrote dtostr to have more precision)
+ Olaf: checked in a new sig* function family (based on rt_sig*).
+ legacy <2.2 signal-handling doesn't work at the moment.
+ Made rudimentary iconv that can convert back and forth between
+ iso-8859-1, utf-8 and ucs-4 (for debugging).
+ Thanks to Markus Kuhn for the excellent utf-8(7)!
+
+0.10:
+ update getpagesize.
+ add personality.
+ add "%*s" and "%*.*s" support to vsnprintf.
+ add putchar (apparently arm-linux-gcc will substitute printf("\n")
+ with putchar('\n') behind your back...?!
+ import include/scsi/ from glibc.
+ add iopl.
+ add execl and sigdelset prototypes.
+ add getopt_long stuff to getopt.h (may compile but won't link).
+ add RPC headers (no code yet).
+ add mlockall, munlockall
+ make "diet gcc foo.c" work.
+ added Sun RPC code and removed as many warnings as possible in a
+ heroic act of self-mutilation.
+ added getproto* and getdtablesize for the RPC cruft :-(
+ added getpass. mount from util-linux actually compiles now!
+ fix the sig*set routines. mount actually works now *bg*
+ fix fwrite dividing by zero when trying to fwrite n records of size 0.
+ added an initial regex implementation (3500 bytes!!!).
+ add llseek and lseek64 with optional lseek fall-back.
+ add res_init.
+ add asprintf (ugh, what an ugly function).
+ expanded arpa/nameser.h to include backwards compatibility defines
+ add ut_name alias to ut_host in struct utmp.
+ add inet_ntop, inet_pton, gethostbyname2.
+ add sysinfo, recvmsg, sendmsg.
+ add endmntent, getmntent, setmntent.
+ fix fnmatch (thanks, Guillaume Cottenceau!)
+ add setenv.
+ remove __restrict from mntent.h, add __restrict__ removal alias for
+ older gcc versions in sys/cdefs.h.
+ add rlim_t, sig_atomic_t declarations.
+ add sigsetjmp #define for __sigsetjmp (oops).
+ (Thanks to Chris Siebenmann for these three bug reports)
+ add a gruesome hack to printf floating point to accept %f and kludge
+ together support for %.2f. Don't look at the code, please!
+ fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
+ imported fix for entlib by Jeff Garzik.
+ add glob implementation from Guillaume Cottenceau (Thanks!!)
+ add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
+ add REG_ICASE and word start/end handling to my regular expressions.
+ my regular expressions now actually match substrings (i.e. "foobar" to "bar").
+ wrap getcwd to comply to man page (the syscall returns the number of
+ bytes, not the buffer)
+ add realpath.
+ fix vfprintf.
+ fix *scanf %s zero termination.
+ add abs, labs, llabs.
+ add <sys/io.h>, ioperm syscall.
+ add flock to <sys/file.h>
+ fixes to bsearch and the regular expressions.
+ add fake herror.
+ add scandir and alphasort.
+ add killpg
+ implemented a gross hack to make libpthread compile when
+ dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
+ add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
+ fix sigsuspend (syscall had completely fscked up arguments!)
+ RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
+ for sending a patch.
+ add getserv*.
+ add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
+ "search" from resolv.conf.
+
+0.9:
+ fixed initgroups (oops)
+ Cleanup appending file open for stdio (thanks, James Antill)
+ imported vfprintf fix from James Antill.
+ add fnmatch
+ change index, rindex and bcmp as weak ELF symbols (were #defined before)
+ Olaf added character classes to *scanf.
+ Put object and library files into a separate directory (bin-$ARCH).
+ Add "cross" make target to make all architectures.
+ Add "diet" program and man page.
+ Add getgrnam, getgrgid
+ Add cfmakeraw (Thanks, Antonio Musumeci)
+ localtime won't call gettimeofday when the tzfile parser is used.
+
+0.8:
+ vsnprintf(0,...) estimated the length of strings with a padding width
+ incorrectly.
+ new reboot() from Olaf.
+ added prototypes for getsockopt and setsockopt.
+ added experimental sem* and shm*
+ define EXIT_SUCCESS and EXIT_FAILURE
+ added setvbuf (only changes mode, not buffer)
+ added dietwarning.h (woohoo, linker warnings!) and used it to warn of
+ insecurity (system, sprintf) or bloat (printf and stdio).
+ added qsort() and bsearch(). Benchmark on 1000 random ints:
+ glibc: 679414 cycles qsort and 3352 cycles bsearch
+ diet libc: 300010 cycles qsort, 553 cycles bsearch
+ I have no idea why glibc is so slow.
+ added __isnan (references by libm.a from glibc).
+ added popen() and pclose(). Now the diet libc can link slsh (from
+ S-Lang!)
+ corrected usleep. It was more of an msleep until now.
+ corrected __dtostr (it looped when trying to format "0.0").
+ several fixes to stdio (thanks to S-Lang's excellent test suite!)
+ added ungetc (does it work?)
+ added inet_aton (yuck!)
+ added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
+ added h_errno and __h_errno_location
+ added inet_ntoa
+ added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
+ add bcopy, index, rindex macros
+ add isgraph and isxdigit
+ add strftime (ugh!!!)
+ Olaf fixed strftime, gmtime_r leap year bug.
+ Jeff Garzik contributed a spec file. I put it in contrib and hope
+ everbody knows what to do with it...
+ Olaf checked in a ton of libpthread stuff.
+ added mkstemp using /dev/urandom (harder to guess than getpid()).
+ add large file backwards compatibility support (so gzip will run on
+ kernel 2.2 and 2.0)
+ added shutdown
+ added nice
+ added pseudo-locale support for is* (they are now weak aliases,
+ isupper -> __isupper_ascii etc). So, for example, liblatin1 can
+ overwrite the default is* functions.
+ added liblatin1.a
+ added tzfile implementation (does it work for anyone else?)
+ added syslog(3) (thanks to Rene Müller!)
+ Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
+ Thanks!
+ merged duplicate code in execv and execvp into exec_lib.o
+
+0.7.2:
+ added several prototypes to already implemented functions and
+ <sys/reboot.h>. Thanks for Abraham for pointing this out.
+ added prototypes for process group and dup syscalls. Thanks to
+ Abraham again. He also contributed an implementation for daemon(),
+ an ugly BSD hack. I decided to diversify the lib/ directory a
+ little and now created a libugly/ directory for stuff like system()
+ and daemon() ;-)
+ added libstdio and moved all that stdio crap from lib/ there. The
+ idea is to start separating now what we will separate for shared
+ libraries anyway.
+ optimized x86 unified-syscall by Olaf.
+ added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
+ limits.h instead)
+ added remove.c and enough cruft to limits.h to make it compile lzo,
+ lzop and bzip2.
+ added mktime, asctime_r, asctime and ctime (needed for gzip).
+ Someone will need to implement a reader for the glibc localtime file
+ format some day (man tzfile, ugh!) :-(
+ added unlink prototype to unistd.h.
+ added gmtime and gmtime_r.
+ fixed sparc unified syscall error handling (please upgrade!).
+ removed readdir glibc compatibility cruft.
+ removed stat glibc compatibility cruft.
+ oops, my fread was broken for pipes.
+ Olaf found a bug in pipe() for sparc, too.
+
+0.7.1:
+ optimized away the static arrays from __ltostr and __lltostr.
+ optimized away the static arrays (and more!) from strtoul and strtoull.
+ added system (by Olaf).
+ added tolower and toupper
+ added getopt from Olaf (~600 bytes on x86!)
+ added clone for mips (by Olaf).
+ fixed longjmp and setjmp on sparc not to require glibc include files.
+ added pause for all (by Olaf).
+ added __attribute__ ((__const__)) to ctype.h
+ added isupper and islower.
+ added putc and putchar as macros.
+ added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
+ insightful discussions and patches I partially used for the last three)
+ added getpriority and setpriority (also by Abraham)
+ oops, I broke strtoul in a recent optimization attempt.
+ oi, setjmp and longjmp were broken on other platforms, too!
+ Thanks to Sébastien Côté for reporting this.
+
+0.7:
+ clone support for i386,alpha,arm and sparc by Olaf.
+ Initial dynamic loading glue for i386, also by Olaf.
+ We don't have a dynamic loader yet, so this is not yet usable.
+ added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
+ vsprintf, writev, all by Olaf.
+ imported readdir fix from Guillaume. Mhh, can the kernel interface
+ really be this broken?
+ Found a kludgy way to detect whether the kernel includes define struct
+ stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
+ not work for you, please tell me!
+ Removed bogus __seek_types enum, it's a bunch of #defines now.
+ Fixed stdio line buffering. The code was already there but I forgot
+ to mark stdio and stdout as line buffered. This should really be
+ done dynamically using isatty, though.
+ Removed superfluous "if (1)" in execvp.c
+
+0.6.14:
+ *scanf did not append the 0 byte for %s.
+ added creat and changed creat to call open directly instead of open64.
+ did for fread what 0.6.10 did for fwrite.
+ repaired buffered stdio a little (line buffering is still not
+ supported).
+ [All of these bugs have been reported by Guillaume. Thanks!]
+ added __pure__ to strchr and strrchr in <string.h>
+
+0.6.13:
+ included COPYING to make clear that the diet libc is covered by the
+ GNU General Public License (and _not_ the LGPL). That means that
+ you need to obtain a license from me if you want to use the diet
+ libc in a proprietary program that you want to distribute.
+ The x86 unified syscall swapped arguments #4 and #5 and noone
+ noticed until now! Thanks to Guillaume Cottenceau for reporting
+ this!
+ The malloc had a subtle bug with small allocations that could cause
+ segfault. Guillaume reported it, Olaf fixed it.
+
+0.6.12:
+ added assert, statfs and fstatfs
+ added include/net/if.h so fget compiles again.
+
+0.6.11:
+ added putenv.
+
+0.6.10:
+ fixed fwrite. It returned the number of bytes written, not the number
+ of records. Thanks to Albert D. Cahalan for pointing this out.
+ fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
+ added brk and sbrk. harold@nb.com.sg made me do it.
+
+0.6.9:
+ fixed execvp not to return on ENOENT
+ did for {open|read|close|seek|tell}dir what I did for stat before.
+ The glibc compatibility part is currently non-functional.
+ fixed white space handling in sscanf " (" would not match " (".
+ fixed printf to accept 'l' flag.
+ fixed getpwuid (ignored last line)
+
+0.6.8:
+ Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
+ mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
+ added strlcpy and strlcat from OpenBSD.
+ added stat64, fstat64 and lstat64.
+ added endian.h and made ending of strlen.c endianness-aware
+ added string routines size tweak to dietfeatures.h. Most of the
+ string routines have been unrolled. This is up to three times as
+ fast but creates up to three times larger code. Now you can disable
+ the unrolling.
+ added sendfile.
+ I also added pread. It works on x86 and sparc but not on ppc and mips.
+ I have no idea what's going on. strace disagrees with the kernel.
+ Can anyone help? I asked the Linux kernel mailing list for help, too.
+ added a few aliases of the type __libc_open for open. nm on
+ libpthreads.so indicates that we will need them.
+
+0.6.7:
+ the sources now compile without warnings with -Wall.
+ printf now prints "(null)" when %s is passed NULL. This can be
+ removed with WANT_NULL_PRINTF in dietfeatures.h
+ added vfprintf, execl, ttyname.
+ stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
+ __dietfstat so they can use the normal kernel struct stat.
+ stat, lstat and fstat are now C wrappers that convert to the glibc
+ struct stat. So we can avoid that overhead for programs that use
+ dietlibc headers.
+
+0.6.6:
+ changed the Makefiles so you can now set CFLAGS on the command line
+ added memccmp (analogous to memccpy) and strncmp.
+ Olaf fixed another bug in the sparc unified syscall.
+ Paul Clifford contributed a C version of his strlen.S that is much
+ more efficient than the previous strlen on all platforms! It also
+ looks like technology from Roswell. ;-}
+ added a "real" stdio. Well, almost. Please contribute!
+ added dietfeatures.h so you can remove features you don't need.
+ removed debug code from vsnprintf that changed \0 to ' ' (argh!).
+ stdio now works with simple programs and minigzip from libz.
+ stdio uses some major trickery to avoid linking the stdio, stderr and
+ stdout (and reserving space for them) when they are not used.
+
+0.6.5:
+ Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
+ most of them bugs in the new header files, but also missing sigset
+ functions.
+ Paul Clifford contributed an assembly strlen.S for ARM and fixed
+ several bugs.
+ Fixed ppc/setjmp and mips/pipe.
+ Olaf contributed a new sparc unified syscall.
+
+0.6.4:
+ declared is* static inline in getservent.
+ added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
+ changed strlen to return 0 when passed NULL.
+ new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
+ Scientist who actually implemented this without access to a MIPS
+ box, just from reading the architecture manual. And it worked out
+ of the box.
+ started a set of system includes, mainly so that I can use lcc and
+ my alpha-linux cross compiler (which is unable to cross-compile
+ glibc). diet libc can now be compiled without any include files
+ from a normal libc. The includes do declare more than diet libc
+ currently delivers and they are still far from complete for real
+ applications.
+ I will only add assembly versions that are smaller _and_ faster than
+ the C version. Larger routines are only accepted if they are called
+ very often and are substantially faster.
+ added i386 assembly strchr, which is smaller and faster than the old
+ version. It is, however, larger than the version contributed by
+ proton (thanks, anyway).
+ added i386 strlen (31% faster, 14% smaller)
+ "make t" will now create a map file called "mapfile".
+
+0.6.3:
+ added sys_errlist, strerror and perror
+ added isblank
+ added atol
+
+0.6.2:
+ mmap for ARM didn't compile. Thanks, Paul!
+
+0.6.1:
+ split mmap into the architecture specific subdirectories.
+ getenv now copes with environ==NULL, thanks Paul Clifford.
+ Paul also contributed a smaller ARM startup code.
+
+0.6:
+ strcat returned the wrong result. Thanks, Dietz Pröpper.
+ strtod now understands a negative exponent (oops, thanks Bertram Barth)
+ Port to arm-linux-gnu, but on the Netwinder I use for testing the
+ __dtostr does not work (I have no idea why!)
+ The MIPS port now uses (much smaller) non-PIC code. That means that
+ the applications you link against diet libc also have to be compiled
+ non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
+ Thanks to Ralf Bächle for helping me with this!
+ I made subdirectories for the architectures and use VPATH to override
+ VPATH so that make finds the source file automatically. That should
+ simplify the sources greatly.
+ Olaf Dreesen contributed Alpha support including setjmp and longjmp!
+ ARM and MIPS now also have setjmp and longjmp
+ "compile" and "load" are now make targets. Use them for djb programs.
+ added contrib/elftrunc.c which will remove unnecessary ELF headers.
+ Again, contributed from Olaf. Great work!
+
+0.5.12:
+ printf also does signed numbers.
+ If you don't use atexit, dietlibc now does not link exit, only _exit.
+ *printf now correctly returns the number of bytes written.
+ Olaf contributed experimental sscanf and vsscanf implementations.
+ If passed NULL as buffer, snprintf will not write anything but still
+ return the number of bytes it would have written.
+ Initial MIPS port! (Oh, the agony!)
+ No setjmp and longjmp support yet! Please contribute!
+ I even implemented unified syscalls for MIPS. Still, MIPS code is
+ almost twice the size of SPARC code. If anyone knows why: please
+ tell me!
+
+0.5.11:
+ I implemented new unified syscalls for x86, sparc and ppc, this time based
+ on .s files and not .c files, and I moved the syscalls into
+ subdirectores to clean the dietlibc sources up a little.
+ A binary consisting of printf("%s is %d\n","olaf",23) is now
+ 2864 bytes on sparc
+ 2488 bytes on intel
+ I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
+ to make a few more applications work.
+ Olaf Dreesen also implemented some unified syscall stuff for x86.
+ He discovered that with our unified syscall interface it actually
+ costs <10 bytes total to make all system calls thread safe!
+ I implemented atexit() (can register up to 4 callbacks).
+ I implemented strtod and __dtostr (the opposite). Now we can add
+ floating point support to vsnprintf and sscanf!
+
+0.5.10:
+ I actually saw that I can not only merge the errno handling code of
+ the system calls on x86, I can also merge the rest (including the
+ arguments) except for setting the system call number. All those
+ system calls are now just a jump to a unified system call handler.
+ I got rid of x86openclose again. The savings are substantial:
+ chown from embutils went from 7664 to 7184 bytes!
+ If I'd move the system call wrappers to assembly language, I could
+ even reduce the alignment (does not matter since it's just a jump
+ anyway) and get rid of the "ret" behind each jump (one byte per
+ system call!)
+
+0.5.9:
+ added memchr, strpbrk, strstr, strtol, isspace (hehe)
+ fixed strdup
+ fixed return values for strcpy and strcat (thanks to Norbert Berzen)
+ Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
+ (no signed integers, only strings and unsigned integers (but
+ supporting octal, hex and decimal). Thanks, Olaf! (by the way:
+ that code must be wonderful, I don't understand it at all *bg*)
+ Olaf's printf does understand padding like in "%08d" and "%8d" and
+ automatically pads pointers with '0'.
+ Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
+ Thanks to proton for inspiration on this.
+ The new x86 start code also does not reference exit any more, thus saving
+ 64 bytes for executables that don't call exit explicitly.
+ [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
+ Moved errno and environ to start.S, saving no byte binary size but
+ speeding up compilation and slightly shortening dietlibc.a ;-)
+ For x86: joined open and close into one assembler file, sharing the
+ errno handling. This is a feasibility test and it actually saves a
+ few bytes. I think I will reimplement the _syscall[1-6] macros on
+ all platforms now to share the errno handling code for them.
+
+0.5.8:
+ fixed strchr to be able to look for 0.
+
+ added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
+ memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
+ strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
+ contributed by Olaf Dreesen)
+
+ added execvp, getcwd
+
+ fixed __xmknod
+
+ Note: can it be that the ftw interface really is so broken that I
+ cannot implement it without having to implement some searching data
+ structure? I included an experimental ftw implementation that will
+ not follow symlinks.
+
+0.5.7:
+ oops, if_nametoindex was broken!
+
+0.5.6:
+ ported to ppc-linux.
+ fixed i386 sigsetjmp (I mistyped the function name)
+ included sigjmp.c
+
+0.5.5:
+ added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
+ actually, it wasn't fork that wasn't working for sparc, it was pipe.
+ I fixed it now.
+ dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
+ fixed readdir to use getdents and not the intel inline asm
+
+0.5.4:
+ ported to sparclinux (sparc32 only). Beware: does not work yet.
+ added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
+
+0.5.3:
+ added tcsetattr and getenv to compile e3
+
+0.5.2:
+ added vhangup, tcgetattr, isatty and memcmp for fgetty
+ (http://www.fefe.de/fgetty/)
+ added localtime from uC-libc.
+
+0.5.1:
+ stat and friends actually work now. Yuck! Another case of
+ translation between kernel and userland. Why can't the kernel
+ people and the libc people simply agree on a standard?
+ removed many unnecessary includes to speed up compilation.
+ added -fomit-frame-pointer and i386 compilation target to reduce code size.
+ inlined socketcall to reduce code size.
+ "load" and "compile" are examples for djb code.
+
+0.5:
+ Olaf Dreesen contributed a much smaller implementation of malloc and friends.
+ each object file is now treated with "strip -x -R .note -R .comment"
+ split each system call into a separate object file
+ added ntohs, htons, alarm, if_indextoname and if_nametoindex
+

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+diet libc FAQ.
+
+
+Q: How do I compile this? I don't see a configure?
+A: Just type make.
+
+
+Q: How do I install it? make install?
+A: Yep. It will then install itself to /opt/diet, with the wrapper in
+ /opt/diet/bin/diet. Or you don't install it at all.
+ The diet libc comes with a wrapper called "diet", which can be found
+ in bin-$(ARCH)/diet, i.e. bin-i386/diet for most of us. Copy this
+ wrapper somewhere in your path (for example ~/bin) and then just
+ compile stuff by prepending diet to the command line, e.g. "diet gcc
+ -pipe -g -o t t.c".
+
+
+Q: How do I compile programs using autoconf with the diet libc?
+A: Set CC in the environment properly. For Bourne Shells:
+
+ $ CC="diet gcc -nostdinc" ./configure --disable-nls
+
+ That should be enough, but you might also want to set
+ --disable-shared and --enable-static for packages using libtool.
+
+
+Q: My program complains about missing asm/* or linux/* header files!
+A: It is quite linux specific. You can try omitting the -nostdinc, but
+ except for some cases conflicts are likely. You should not be using
+ the kernel headers in your software.
+
+
+Q: Do you have cross compiling support?
+A: Yes. Just type something like "make ARCH=arm CROSS=arm-linux- all".
+ For arm, alpha, mips, ppc, sparc and i386, shortcuts exist. You can
+ also use "make arm", for example. You still use the same "diet"
+ program as for normal compilation, but you can then say
+
+ $ diet sparc-linux-gcc -pipe -g -o t t.c
+
+ Programs using autoconf can be configured like this:
+
+ $ CC="diet sparc-linux-gcc" ./configure --disable-nls
+
+
+Q: There are a few warnings about possibly uninitialized variables when
+ compiling the diet libc. Can't you remove them?
+A: This type of warning can only be removed by a) compiling without
+ warnings or b) initializing the variables in question. In all cases,
+ the variables won't actually be used uninitialized, but adding an
+ explicit initializer will add a few bytes of code. As you know, the
+ goal of the diet libc is to not waste a single byte of code, so we
+ don't add initializers ;-)
+
+
+Q: When linking binaries, I get warnings about stdio and printf all the
+ time. What gives?
+A: Since the diet libc was written to make writing small programs
+ possible, it also tries to assist in the process of seeing causes of
+ bloat. Premier causes for bloat are stdio and the printf family of
+ functions. The diet libc will also warn you if you still use
+ assert() (which is normally not enabled in production code) or if you
+ use functions that use static buffers (like gethostbyname and
+ friends).
+
+
+Q: My program stopped parsing command line arguments properly! Now what?
+A: The getopt in the diet libc adheres to the Single Unix Specification.
+ In particular, it initialized optind to 1 (not 0) and breaks if
+ someone sets optint to 0 (as some misguided legacy programs to).
+ Also, it does not reorder arguments, i.e. something like "rm -f foo -v"
+ will not see -v as option but rather as non-option argument. If you
+ need GNU getopt behaviour, please use GNU getopt instead of the diet
+ libc code.
+
+
+Q: I get linker errors about missing __ctype_b!
+A: This happens when you link in code that was compiled with the glibc
+ headers. The most common culprit is a library like -lncurses,
+ -lcrypto or -lresolv. All external libraries you use have to be
+ compiled with the diet libc headers (CC="diet gcc"), and there is no
+ libresolv with the diet libc, it's in the main libc!
+
+
+Q: My program links, but when I run it, I get no output at all and it
+ appears to terminate immediately.
+A: This normally happens if you link in glibc. The major reason for
+ this was that shared libraries were linked in. diet sets -static
+ since version 0.13, so if it still happens to you, you need to strace
+ and debug your software.
+
+
+Q: Why aren't you compatible to glibc? I thought the interface was a
+ standard?
+A: Yes, the interface is, but a lot of details are missing. For
+ example, the diet libc uses a different "struct stat" layout than
+ glibc. We use the one from the kernel, glibc uses an own one and
+ links in translation code. This is part of the reason why glibc is
+ so big and ugly. If we support all of this, we end up as bloated as
+ glibc.
+
+
+Q: Where is the test suite?
+A: The humble beginnings are in the "test" directory, but it can't be
+ run automatically yet.
+
+
+Q: GPL sucks! Now I can't compile my BSD programs with the diet libc!
+A: Wrong. You can compile them, and you can use them. You just can't
+ redistribute the binaries. If you are a distribution vendor and want
+ to use the diet libc to make BSD licensed binaries for the install
+ or rescue floppy which you sell commercially, please talk to me.
+
+
+Q: Where are the shared libaries? make install didn't install them!
+A: You have to explicitly build them with "make dyn". Since they are
+ experimental and only supported on a small subset of the platforms,
+ that is not default. Also, I recommend you only use shared libraries
+ if you really know what you are doing. For example, you can't just
+ use your system shared libraries, because they have a dependency on
+ glibc in them, so the program will crash. And you have to explicitly
+ compile the code with -fPIC or -fpic. You can then use them by
+ substituting "diet-dyn" for "diet" on the command line.
+
+
+Q: My target platform does not have a MMU. Should I be using uClibc?
+A: I am not aware of any issues with MMU-less systems. You should be
+ able to use the diet libc just fine. Having a MMU or not is mostly
+ an issue for the kernel, not libc.
+
+
+Q: How do I make myself a cross compiler?
+A: untar binutils and gcc (I used version 2.11.2 and 3.0.4 respectively)
+ Then use the --target=arm-linux (or whatever platform you want)
+ configure options. For gcc, add --enable-languages=c (otherwise gcc
+ will try to make C++, Objective C and Java, too, and those
+ compilations will fail because they require installed libc headers
+ which you don't have yet). I recommend using --enable-static
+ --disable-shared, too, because otherwise the binutils shared
+ libraries will overwrite each other if you install more than one
+ cross binutils for different targets.
+ binutils$ ./configure --enable-static --disable-shared --prefix=/opt/cross --target=arm-linux
+ gcc$ ./configure --enable-static --disable-shared --prefix=/opt/cross --target=arm-linux --enable-languages=c
+ For some platforms, gcc compilation will fail while trying to compile
+ some part of libgcc.a because it depends on some libc header file.
+ This is a gcc bug and you should complain using gccbug, because you
+ can't cross-compile libc unless you successfully installed the cross
+ compiler.
+
+
+Q: Where are the xdr_* symbols?
+Q: Where are the RPC symbols?
+Q: util-linux says that rpcgen output does not work?!
+A: Add -lrpc. The code is from Sun and frankly it is so ugly and so
+ rarely used that I don't want to include it in libc.
+
+
+Q: I am missing some BSD/GNU extension!
+A: I started adding a few of them to libcompat. You have to link it in
+ manually, though, as using them is bad for portability and I want
+ people to make a conscious effort to write non-portable applications
+ by not including them in the libc itself.
+
+
+Q: I'm just starting with the diet libc. Should I use the tarball or
+ the CVS version?
+A: Always use the CVS version. We generally don't add unstable test
+ stuff on the CVS tree, and our APIs are stable (they are
+ standardized, remember?). In fact, we don't add much stuff at all.
+ Most changes are bug fixes and optimizations, and in general you'll
+ want those.
+
+
+Q: Does the diet libc support profiling (with gprof)?
+A: There is experimental support for profiling, but so far it only works
+ on x86. To use it, do "make profiling" before make install. Then,
+ diet will link in the support code if it finds a -pg on the gcc
+ command line.
+
+
+Q: I get compiler errors in a line with caddr_t, u_long, n_short or
+ nlong or similar.
+A: Add -D_BSD_SOURCE to the compiler command line. The diet libc tries
+ to encourage portable and standards compliant programming, so it
+ hides these legacy BSD types from the standard name space. The
+ reason is that the Single Unix Specification contains a specification
+ of the socket API but does not mention those types.
+
+
+Q: I get compiler errors in a line with u_int8_t or similar.
+A: Add -D_GNU_SOURCE to the compiler command line. See previous
+ question. This is a very questionable GNU extension. The C Standard
+ defines uint8_t, uint16_t and uint32_t. Use those instead.
+
+
+Q: Can I compile or use the diet libc with a compiler that is not gcc?
+A: Compile: no. Use: yes.
+
+
+Q: Can you please port the diet libc to FreeBSD/Solaris/Windows?
+A: No.
+
+
+Q: Why do you support non-embedded platforms like IA64 and x86_64?
+A: The diet libc is also useful for servers because it can improve
+ performance by an order of magnitude for certain programming models.
+ Please see http://www.fefe.de/fnord/ (in particular .../fnord/SPEED)
+ for an example and/or read http://www.fefe.de/talk.pdf for some
+ benchmarks.

+ - provide start.S (the start code, look at glibc)

+The diet libc was written with small code and embedded devices in mind,
+not with security for network servers.
+
+Of course we still try to avoid buffer overflows, but there are some
+parts of the code where tradeoffs have been made. This file is meant to
+document them.
+
+ 1. The DNS routines do not check whether the answer came from the IP
+ of the DNS server. The rationale is that people who can sniff the
+ network to find out the query, source port and DNS sequence number
+ can also spoof DNS packets to appear to come from the server we
+ asked, so it does not actually increase security to have that
+ check.

+The malloc code was done by Olaf Dreesen, who also helped with the SPARC
+start code and fork(). Olaf also did the printf and scanf routines and
+he implemented pthreads (wow!) and his now writing a dynamic linker, and
+he ported the diet libc to S/390.
+
+Thomas Ogrisegg ported the diet libc to PA-RISC and IA64 and fixed a few things.
+
+I initially took some syscalls from Redhat minilibc, but the code has
+been completely replaced now.
+
+I initially took localtime and the directory reading routines from
+uClibc, but the code has been completely replaced now.
+
+syslog and crypt were contributed by René Müller.
+
+Jeff Garzik contributed {get,set}{pw,gr,sp}ent.
+
+Uwe Ohse went through the code and fixed many bugs.
+
+Frank Klemm contributed the math library and a lot of correctness and
+smallness patches and rewrote many functions in ix86 assembly language.
+
+Erik Troan found several important bugs and sent in patches to fix them.
+
+I also grabbed code from glibc (mostly assembly routines), and looked at
+the OpenBSD libc for inspiration.
+
+Michal Ludvig did the porting to x86_64 and Gwenole Beauchesne helped
+finish the port.
+
+Johannes Stezenbach improved the MIPS port.

+ - "locale"

+ - improve code size and quality with __restrict__.
+ - FPU exception handling (for mawk)
+ - res_mkquery should not assume op is QUERY
+ - syslog
+ - gethost/netent -> parselib?
+ - Look at qsort (the make test suite exhibits the worst case)
+ - Make __dtostr do scientific notation.
+ - fix %g in printf. They are more or less completely b0rken (in
+ particular rounding the last digit does not work).
+ - qmail-queue dumps core since we added vfork. Editing fork.h to #define
+ vfork to fork works. What happens here?
+ - use TCP if buf[2]&2 is non-zero in DNS answers.
+ - look at mktime: "Falls tm_isdst == -1 gesetzt, so sollte mktime
+ versuchen herauszufinden, ob Sommerzeit eingestellt ist (und laut linux
+ manpage auch tzname setzen), ansonsten die angegebene DST
+ berücksichtigen."
+ - better rand()?

+ - printf %e
+ - move DNS stuff to libresolv.a?
+ - x86_64: readdir fails their test (Gwenole Beauchesne)
+ - regular expressions standards compliance; test suite from AT&T
+ - fgetpwent (needed for cvm)

+.TH diet 1 "April 2001"
+.SH NAME
+.PP
+diet \- mangle gcc command line arguments
+.SH SYNOPSIS
+.PP
+.B diet [-v] [-Os]
+[\fInormal gcc command line\fP]
+.SH DESCRIPTION
+.PP
+diet is a small wrapper around gcc. It will try to look at the command
+line you specify and try to mangle it so that gcc will compile against
+the diet libc header files and link against the diet libc itself.
+
+diet tries to be smart for cross compiling. If the first argument is
+not gcc but sparc-linux-gcc, diet will guess that you want to cross
+compile for sparc and use bin-sparc/dietlibc.a instead of the dietlibc.a
+for your default architecture.
+
+The -v option will make diet print the modified gcc command line before
+executing it.
+
+When passed the -Os option before the gcc argument, diet will mangle the
+gcc options to include the best known for-size optimization settings for
+the platform.
+.SH FILES
+~/.diet/\fIcompiler\fR may contain compiler options as you would
+specify them on the command line, i.e. separated by spaces. Those will
+then be used instead of the built-in defaults for diet -Os.
+.SH AUTHOR
+Felix von Leitner <felix-dietlibc@fefe.de>
