I don't see why that would be necessary.  If the input says '%error'
then it is clear that the user desires an extension.  As far as I can
see, POSIX doesn't require a diagnostic in that case, and I don't
think we need to generate one.

The only reason we would need POSIXLY_CORRECT is if we want the
default behavior to be something other than what is required by POSIX.
I don't yet see a need for that.
