Setting CC to your C compiler should work

The culprit looks like numpy/core/include/numpy/fenv/fenv.h, which is
odd, as I don't see how it would be included -- it's only used for
cygwin. I would think there would be no floating point environment
support included, as the system <fenv.h> is only included when one of
__GLIBC__, __APPLE__, or __MINGW32__ is defined.
See if the attached patch helps.
