       That's a difference.  Dare I suggest fixing GDB?

       I see this as a deficiency in the debugger, 

   How?  The debugger never sees the macros and it would be unrealistic to
   have it to macro expansions even if it did.

So unrealistic that gcc even has a documented option which is supposed
to provide such information for a debugger:

`-gLEVEL'

 ...

     Level 3 includes extra information, such as all the macro
     definitions present in the program.  Some debuggers support macro
     expansion when you use `-g3'.
