Where is _HUGE defined?

[ilovecad]

Hi,

In math.h, there is a declaration:

#ifndef __assembler /* Protect from assembler */
_CRTIMP extern double _HUGE;
#endif /* __assembler */
#define HUGE_VAL _HUGE

but where is _HUGE defined?
I got an unresolved external symbol error when using
HUGE_VAL.
Can someone tell me how to solve the problem?

The _HUGE var is defined in huge.obj contained in libcd.lib from RTL (ask VC++ map file generation). This library is automatically linked in my VC++ 6.0 projects...

Some addition: libcd (with d) in debug mode. It's a standard RT library.
