Function declaration without definition are skipped

[Arnaud Diederen]

Hello all,

I'm considering using emacs + global for C++ development (under linux), and I've run into what's probably a pretty annoying issue for me.

I am working on a C++ project that uses an SDK, of which I only have the header (.h) files. 
Those header files contain many function declarations, and a few inline function definitions.

It appears that only the definitions are indexed by global. 
I presume this is normal (expected) behaviour, as I tried googling for it, as well as searching in the mailing lists (help & bug), but couldn't really find an answer to my problems.

Let's say I have the following 2 files:

--- test.h ---
int test();
int test2();
--------------

--- test.c ---

#include "test.h"

int test2() 
{
  return 0;
}

int main()
{
  return 0;
}
--------------

Then, from my shell:
--------------
address@hidden:/tmp/global-test$ gtags 
address@hidden:/tmp/global-test$ global test
address@hidden:/tmp/global-test$ global test2
test.c
address@hidden:/tmp/global-test$ global -f test.c 
test2               4 test.c         int test2() 
main                9 test.c         int main()
address@hidden:/tmp/global-test$ 
--------------

So, I was wondering whether there was a way to tell global to keep track of functions declarations, even though their corresponding definition is not found?
..this would obviously be helpful for me, for API browsing purposes.

Best regards,
