Mandrake has a heavily patched gcc 3.3.1 with amd64 support. I don't
think it's a compiler issue, I think the assembler code isn't
compatible with amd64:
gcc -Wall -O4   -pipe -ffast-math -fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o i386/cputest.o i386/cputest.c

I get the same error with today's CVS of MPlayer and without the
optimization options. 

I've received a patch from one of the MPlayer developers that changed
the popl opcodes in the lines above to pop, this makes it possible to
compile that file, but the next source (i386/dsputil_mmx.c) gives me
even more errors:

gcc -Wall -O4   -pipe -ffast-math -fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o i386/dsputil_mmx.o i386/dsputil_mmx.c
