About two years ago I ported an app that relies on nan, etc. from CW 
to Xcode. The main problem is (as far as I remember) that isnan, 
isinf and similar functions always return false if __FAST_MATH__ is 
on. Quesa does not use these functions.

BTW CWs "Relaxed IEEE Floating Point" setting works perfectly well with nan.
