Maybe try changing line osg/Math line 195 to
#if defined(__APPLE__) || defined(__CYGWIN__)
FYI I am traveling and don't have access to a Cygwin installation
to test this
Or this might be better
inline bool isNaN(float v) { return ::isnan(v); }
inline bool isNaN(double v) { return ::isnan(v); }
If this doesn't work I suggest asking on the Cygwin list
