I'm not sure I understand your comment. Are you telling that this is
unlikely? I agree, this is not a very big point.

Another reason it's more stable, is, that it never allow the optimizer to
mess with your ident strings.
Any conforming compiler MUST let you see all files used in the executable.

I didn't understand how, eg, my C++ scheme don't work. I think it should
work even if you're including the $Id$ strings in the headers files.
