STATUS: incomplete but should work (or not... I had a lot of heisen-bugs...) + On non i386 archs the kernel header have major differences... + NO workaround yet for this problems... + +It's like linuxthreads a clone base thread implementation. + +I have implemented a "Manager Thread" with all the pain it involves... +Nested thread creation is now working fine... + + +2. HOW-TO make this lib: + + 1. generate the dietlibc in the parent directory. + and make sure you have WANT_THREAD_SAVE active in the file: + dietfeatures.h + + 2. change back here and type make + + and then you should have a libpthread.a + + +3.
