Versions and machine-gmon.h are only partially FPU-dependent, and
you've missed the setjmp code which is also partially FPU-dependent.

If this is really important to people, I can move it up on my priority
list, but right now I'm a little busy.  It also doesn't help that I
have no way to test the result, since I don't have any machines
without a FPU.

I don't understand what people want this for.  What systems do you
have that are so large that they can run glibc, but so small they
can't run a FPU emulator???
