Gcc -Wall won't emit an unused variable warning even without the
__attribute__((unused)).  I.e.,

static const char rcsid[] = "$Id$";

That's the only combination of static, const, char, *, and [] that
I've found that doesn't the emit the warning, so I've always assumed
it to be a deliberate feature.  At least, I hope it is, since we use
that form in all of our code for $Id$.
