I'm trying to compile a program that uses NAN. It includes math.h which
I'm told C99 says should define it. I've grepped the entire source tree

Trying to compile the program yields "error: `NAN' undeclared (first use
in this function)".
Can anyone point me in the right direction?
#ifndef NAN
#define NAN (0.0/0.0)
#endif

GDB has a 'break' feature; why doesn't it have 'fix' too?
I'm told that math.h should do this for me. Moreover, I think NAN is a
machine dependent value.
Adding the line you mention would break on VAX (assuming I understand
this correctly). Although I don't think anyone would run this program
on a VAX, if it's in the ports tree there's the possibility.
Worst case, I could add those defines though.
Thanks.

Have you tried using grep in the library tree to find it?
