Description: 
xfree86 compile breaks with -march=pentium4 -sse2

we need to drop down the CFLAGS to -march=i686, can someone investigate?

First note,  if this is gcc 3.2.x you shouldent be using p4 optimizations,
there buggy. switch to gcc 3.3 if you want p4 optimizations. a p3
optimization will work fine.  this is not a problem with xfree86 but
mostlikley a gcc issue.

I will add something to the BUILD file to look for P4 opts and sse2 and
drop it doewn to i686 so that other opts arent affected, might take me a
few days to get to it though.

works fine here (gcc 3.3.x)

Just heard that it's only -sse2 that breaks it, apparently someone had it
compile with -mcpu-pentium4 but without -sse2.!
