While the format checking supports genuine GNU extensions in glibc (where
they do not conflict with the standards), it doesn't support features that
just happen to be accidents of the current implementation.  The glibc
manual is quite explicit that the 0 flag is not defined for %p, so this
counts as an implementation accident, not a feature that GCC should
support.
