Eric, thank you for your reply however I can confirm that for me this test
does not work on emacs version 24.3.1 Windows build using cedet version from
~~ 26th January.

This is the exact code:

=== CODE ===
#include <iostream>

#define WITH_TESTS
#define SW_VERSION 22

int main ( void ) {

#if ( SW_VERSION >= 22 )
   std::cout << "Version 22" << std::endl;
#endif /* ( SW_VERSION >= 22 ) */

#if defined ( WITH_TESTS )
   std::cout << "WITH_TESTS" << std::endl;
#endif /* define ( WITH_TESTS ) */

   return 0;
}

#if ( SW_VERSION >= 22 ) &&  ( defined( UNIT_TESTS ) )
void someFunc( void ) {
   return 1;
}
#endif /* ( SW_VERSION >= 22 ) */
=ENDCODE ===

When I take out the compound preprocessor check and make it:
===EX===
#if ( SW_VERSION >= 22 )
void someFunc( void ) {
   return 1;
}
=END EX===

Then run C-c , , - I can see with the help of global-decoration-mode that
the function has been picked up.

When I put the compound check in and run C-c , , the function does not get
picked up.

I guess I can check on Ubuntu later on.
