The problem here is that cpp is not detecting that isnan is actually a
macro function, not a normal function prototype. The blitz code uses
#ifdef isnan
to attempt to detect this situation, but it doesn't work. Is there a
cpp guru out there who knows the proper way to detect whether something
is a cpp macro function or not? I've tried a few ideas, but no luck
thus far. Any help would be appreciated.
Thanks, Julian C.
