I prefer a self-contained workaround.  If someone loads a program into
a debugger to fix a problem, they shouldn't have to sift through documentation
to find something like this out--and they probably will end up mailing
the program's maintainer instead, as the result of not doing this looks like
a bug.  `It's similar to a recent locale problem discussed on mutt-dev; one of
OpenBSD's "YES" regexes was "^[Yn]"; someone suggested adding a --without-
autoconf toggle to disable using this string--but I'd certainly never have
thought to look for a manual fix.

Also, that'd be printing "no symbol" errors for other programs (and "no
symtab" errors for empty gdbs).
