math.h will includes architecture/{ppc,i386}/math.h.
These file defines finite but surrounded by #if shown here.

#if !defined( __STRICT_ANSI__) && !defined(_ANSI_SOURCE) &&
(!defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE))

You may not like the idea to add:

#ifdef __cplusplus
extern "C" {
#endif

int finite(double);

#ifdef __cplusplus
}


into epicsMath.h in os/Darwin directory. But seems simpler in this case.
