I for one would love it.  Plenty of times I've wanted macros like:

#define trace(...)  if (TraceFlag) fprintf(stderr, ...)
#define crash(rc,...)  { fprintf(stderr,...); return(rc); }

etc. etc.

This seems like it would be a simple and useful addition to the preprocessor,
and one which could be implemented in a fairly painless way.  Would it really
be that difficult to add to the standard?  (No flames please, that's a 
serious question based upon my own ignorance :-)

One yes vote here...
