I'm all in favor of replacing the macros w/ GG_INLINE function calls.
Note, however, for Microsoft VC++:
  The compiler cannot inline a function if:
     * The function has a variable argument list. 
     * The program takes the address of the function. 

In particular, replacing the TRACE macros w/ inline functions is 
probably not a good idea.

Though, I believe the following construct may work for the TRACE
macros on all platforms:

#define TRACE  (!verbose) ? (void)0 : gprintf
