It is not a regression.  I said "ignore" because he also said
"he couldn't modify the source".  The REAL way to get rid of 
the warning is to mark the thing __attribute__((unused)).

Or even better, __attribute__((used)).  If he fails to do this,
then at some point GCC will stop emitting that variable to the
object file entirely, precisely because it isn't used.

This would be considered a feature for any other variable,
and I can't stomach making bletcherous special cases for a 
variable named "rcsid".
