Sounds right to me.

Thanks for this;  this gives me a clearer idea of how things might
be solved.

It's a little bit messy:  some bits of pymath.c (hypot, and possibly
copysign) are needed in the core, but only on platforms whose
math libraries haven't caught up with C99.  The rest is only
(possibly) needed in the math and cmath modules.  In fact,
on OS X none of pymath.c is needed at all, which results in
lots of "ranlib: file: libpython2.7.a(pymath.o) has no symbols"
in the build output...

I'll try to find a non-hackish solution.
