Hi,

I tried the code from your image:

#include <stdlib.h>
#define ON 0
#define ABC ON

#if ABC
int abc();
#endif

void main() {


}

#if ABC
int abc()
{
   return 0;
}
#endif


and I can flip the #define of ON to be 0 or 1, and it will parse or not 
parse the function at the end correctly.

In fact, there is an existing test in the CEDET repository 
(tests/cedet/semantic/tests/testsppcond.cpp) that has even more levels 
of indirection.

Semantic uses the `hideif' package for handling all the #if macros 
determining if they should have the contents parsed or not.  Since you 
are using Emacs 24.4, and I am using Emacs 24.3, there is perhaps a 
change in hideif that is causing this problem.

I'm assuming this is true because the emacs-bzr-linux build failed the 
test on Aug 26, but passed on Aug 24th.

Perhaps someone who is familiar with 24.4 changes can help out?

Eric
