If it's confusing, let's add a comment. That would be better than 
unnecessarily duplicating the actual code.

Yes, and we should minimize dependencies on those macros as well. The 
same principle applies to all these conditional flags - generally 
speaking the fewer uses of these macros, and the fewer distinct copies 
of the code, the better.

We could even dump those two macros entirely. But this would be a bigger 
project, one I lack time for (though perhaps Mattias has time...).

Oh, I do that all the time too, with both Emacs and other programs. It's 
OK. Why refuse help from GDB?
