think it can be simplified quite a bit. The old code includes <cmath> for pre-10.2 and anything using something other than g++ 4 and then uses std::isnan. For the most current version, it leaves out cmath and uses isnan(). std::isnan and cmath work for the current version, so I just made it include cmath if __APPLE__ is defined and removed the ifdef between versions of OS X for isnan related things. This way the code is all the same, and it's not fragile to someone including <cmath> prior to including osg/Math."
