Hello Curt,
could you please revert this change and remove the whole FreeBSD
clause - it just makes life harder on the cuurrent FreeBSD RELEASE - or
change it. See below.

An alternative to keep compatibility with older FreeBSD releases might
be to place such a clause:
#if defined (__FreeBSD__)
extern "C" {
#if __FreeBSD_version < 500000
inline int isnan(double r) { return !(r <= 0 || r >= 0); }
#endif
}
#endif
Thanks alot,
Martin.
