I find:
	static const char rcsid[] = ...

How long will it be before the ANSI compilers start discarding unreferenced
static data?  Or is "rcsid" already a special case in gcc?  :-)

Should we switch to #ident?  It doesn't do anything useful on 2.1.5, but
we could fix that.

	#ident "$Id: frobble.c,v ..."

What does the C standard say about #ident?  Has anyone put a copy of the
standard on the web?

Stephen.
