Nah, that also effectively assumes the GNU libraries. Here's a better
idea:

#include <math.h>
int mpl_isnan_f(float f)        { return isnan(f); }
int mpl_isnan_d(double f)       { return isnan(f); }
int mpl_isnan_ld(long double f) { return isnan(f); }

Compile this as C(99), not C++, and put

extern "C" {
  int mpl_isnan_f(float);
  int mpl_isnan_d(double);
  int mpl_isnan_ld(long double);
}

in the C++ file.
