NM. Just change the isnan(v)'s to __isnanf(v) and __isnand(v) and it
works. :)

Subject: [osg-users] isNaN() breaking compile under Cygwin
Hello.
Using the latest download with the 3.3.3 gcc under cygwin (just installed
cygwin and the latest 1.2 stable zipfile of osg: Producer and Inventor
compiled fine, but compiling OSG, I get:
Entering directory src
make[1]: Entering directory `/home/Steven/OSG_OP_OT-1.2/OpenSceneGraph/src'

In Math:200 I see:
inline bool isNan(float v) { return isnan(v); }
I guess that Cygwin doesn't like this, or perhaps I need to install more
cygwin stuff?
