I know this is slightly off-topic, but I just stumbled across some fairly recent MinGW stuff that might be of some interest to somebody:
gcc-4.2.2 native win32: http://sourceforge.net/projects/tdm-gcc/
gcc-4.2.1 + mingw toolchain native win32 : http://sourceforge.net/projects/mplayer-win32/
gcc-4.2.1 mingw-cross for linux: http://sourceforge.net/projects/mingw-cross/
( I haven't tried any of these personally. )
