I've added an #ifdef that causes the file content to be skipped. I
prefer #ifdefs over automake conditionals since the latter tend to
slow down the build and clutter the Makefile.am.

So config.h defines USE_MMX for you? Looks as if we have to improve
the configure test. The check we use now is copied from DirectFB and
seems to work there. In DirectFB we include the assembler code as
__asm__ __volatile__ ()
while the new code in The GIMP seems to be using
I don't know this stuff good enough to know the difference, but I'd
say we need to change the configure check so that is uses the same
asm constructs that the code in app/composite is using.
