These two game engine headers includes other headers that include 
various c and c++ headers, so probably ctype.h that defines an isspace 
macro, is included somewhere before a c++ header defining an isspace 
inline function.

A solution (as already posted in april 2005) is to #undef the isspace 
macro. But with all these nested includes it's hard to get a good 
overview of what is included when, so maybe you could try putting this 
at the top of the c++ file that has the compile error:

#include <ctype.h>
#undef isspace

ctype.h won't be included again because of the #ifndef _CTYPE_H_ / 
#define _CTYPE_H_ stuff, so hopefully the isspace macro then won't be 
defined again either.
