It does crash with gcc 2.95.3-10 and --disable-streaming:


gcc-2.exe -c -O4 -march=k6 -mcpu=k6 -pipe -ffast-math 
-fomit-frame-pointer -D__C
YGWIN__ -I../loader     -o demux_mov.o demux_mov.c
gcc-2: Internal compiler error: program cc1 got fatal signal 11
make[1]: *** [demux_mov.o] Error 1
make[1]: Leaving directory `/home/Administrator/tree/libmpdemux'
make: *** [libmpdemux/libmpdemux.a] Error 2
{standard input}: Assembler messages:

inserted

Hmm, what about just removing that #ifndef?  gcc 3.2 is the standard 
compiler on Cygwin nowadays and we have a tradition of not bowing to 
compiler errors ;-)  Besides getting rid of an #ifdef is always nice, so...
