Sorry, on mac OS X in Core Defs.h (around line 250) with this fix:

#ifdef PLATFORM_WIN32
inline bool IsNaN(double d)        { return _isnan(d); }
#elif PLATFORM_OSX11
inline bool IsNaN(double d)        { return std::isnan(d); }
#else
inline bool IsNaN(double d)        { return isnan(d); }
#endif

upp compiles. Otherwise not. Do you think this fix is ok? Or should someone dig deeper as in here: http://stackoverflow.com/questions/2249110/how-do-i-make-a-p ortable-isnan-isinf-function?

AFAIK, it can just be

inline bool IsNaN(double d)        { return d != d; }
