There's always cat :-)
(oh wait, I guess I need two smiley faces for that suggestions :-)
A big part of the problem is that there's no way to do '#define
foo(x)' on the command line (correct me if I'm wrong). You can do
'#define foo' on the command line, but that leaves calls of foo
expanding to (x). You'd have to have __IGNORE (to go back to bde's
example) defined in cdefs.h. And if you are doing that, then why not
have __RCSID defined too. It's not like it pollutes the application
name space :-).
