+For Mageia I ran it on the latest release so you could evaluate that by compiling using my source file from my web site. I didn't make any change to the setup build  except that my directory is  /home/michel/packages
+
+in .rpmbuild on SL6
+
+%_topdir %(echo $HOME)/packages
+
+in .rpmbuild on mageia
+
+%_topdir %(echo $HOME)/packages
+%_tmppath %(echo $HOME)/packages/tmp
+

+
+To compile it you need to have mpfr, gmp and mpc installed. Codesourcery, Atmel and Microchip add those with their proprietary versions of gcc but I do not.
+I think that they would conflict with the local ones and they make it longer to compile the compiler anyway.
+
+If you get the idea to compile the PIC32 stuff remember that it looks for a particular include file that Microchip didn't bother to have with their source code.
+You need to install Microchip's compiler and make a link to the include files
+
+lrwxrwxrwx 1 root root 45 17 janv. 23:25 /usr/pic32mx/include -> /opt/microchip/mplabc32/v2.02/pic32mx/include
+
+MIPS and ARM code are not fully tested yet so if you have issues with them feel free to complain to me for fixes. Testing is in progress on ARM version.
+As for the MIPS stuff the idea is to get the debugger for PIC32 so for kicks I generated the other binaries.
