G'day all,

I can't get current SVN to compile at all here (same problem with regard to register spill other people are seeing). I applied Blue Swirls patches (as seen here http://lists.gnu.org/archive/html/qemu-devel/2008-03/msg00320.html) and cleaned up the rejects, but I just get stumped further on...

gcc-3.4 -fomit-frame-pointer -I. -I.. -I/tracks/src/src/qemu.new/target-i386 -I/tracks/src/src/qemu.new -MMD -MP -DNEED_CPU_H -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -I/tracks/src/src/qemu.new/tcg -I/tracks/src/src/qemu.new/tcg/i386 -I/tracks/src/src/qemu.new/fpu -DHAS_AUDIO -DHAS_AUDIO_CHOICE -I/tracks/src/src/qemu.new/slirp -march=pentium-mmx -Wall -O2 -g -fno-strict-aliasing -m32 -c -o helper.o /tracks/src/src/qemu.new/target-i386/helper.c

I'll download and compile a specific compiler if there is one guaranteed to compile cleanly (or even work at all). What compilers are the major developers using that actually function?
