This resolves several warnings when compiling with MinGW because isnanf is not in MinGW's math.h (it's not a standard C function). On the other hand, isnan is a widely available C99 macro designed for both floats and doubles. We also have an isnan implementation in libs/port/isnan.c for pre-C99 compilers.
