System: Linux gromit 2.4.0 #58 Fri Jan 5 18:22:21 CET 2001 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: /cvs/gcc/configure --prefix=/opt/gcc-2.97.test --enable-shared --enable-threads=posix --with-gnu-as --with-gnu-ld --disable-nls --with-system-zlib --enable-languages=c,objc,c++,f77
>Description:
	Invoking GCC on i686 with -msse or -mmmx gives an internal error
>How-To-Repeat:
	Just use -mmmx on any program and you get:
/opt/gcc-2.97.test/bin/gcc -msse /tmp/t.c
