gnumach doesn't support newer fpu state for mmx/xmm et al.
would need new thread state flavor for "fpx" or whatever we call it.
cf linux asm/user.h user_i387_struct vs user_fxsr_struct
former is what mach can handle. need to handle latter in ctx sw + user
thread state flavor, then enable cpu sup
show x/i $pc or similar, maybe disas $pc at the fault.
Presumably the fxrstor insn. Check the mxcsr value.

Heya gang,
I was able to build gcc-4.1 with a crtfastmath.o by changing config.gcc
to the following:
i[34567]86-*-gnu*)
tmake_file="${tmake_file} i386/t-crtfm"
;;
But when running the attached test code compiled with --fast-math, I get
the following:
Starting program: /devel/
