Please also add some tests of format checking for these modifiers in
gcc.dg/format/gcc_*.c.
The following patch does that.
Haven't added tests for bad type (but I think we don't have them in
c99-printf* either) for these because it is hard to figure out what
type from {,unsigned }{int,long,long long} size_t/ptrdiff_t certainly
is not, guess one could do that with preprocessor conditionals, e.g.
comparing __PTRDIFF_MAX__ with __INT_MAX__, __LONG_MAX__ and
__LONG_LONG_MAX__ and pick up the one which is different; but we'd need
to find out corresponding effective targets for the expected diagnostics.
Tested on x86_64-linux and i686-linux, ok for trunk?
