As Norman pointed out include/osg/Math.
Compare the beginning lines to these lines (the first and last lines (inline
and template are untouched and not sure of the rest):
inline double round(double v) { return v>=0.0?floor(v+0.5):ceil(v-0.5); }
#if defined(WIN32) && !defined(__CYGWIN__) && !defined(__MWERKS__)
inline bool isNaN(float v) { return _isnan(v)!=0; }
inline bool isNaN(double v) { return _isnan(v)!=0; }
#else
#if defined(__APPLE__)
inline bool isNaN(float v) { return std::isnan(v); }
inline bool isNaN(double v) { return std::isnan(v); }
#else
// Need to use to std::isnan to avoid undef problem from <cmath>
inline bool isNaN(float v) { return isnan(v); }
inline bool isNaN(double v) { return isnan(v); }
#endif
#endif
/** compute the volume of a tetrahedron. */
template<typename T>
This is the way I modified mine for Cygwin
