	PR testsuite/25241
testsuite/
	* gcc.dg/cpp/20000625-1.c: Without dg-options the default is
	-pedantic-errors, so we should match errors.
	* gcc.dg/cpp/escape-1.c: Likewise.
	* gcc.dg/cpp/charconst.c: Empty character constants are errors.
	* gcc.dg/cpp/direct2.c: This is a mandatory error instead of a
	warning.
	* gcc.dg/cpp/endif-pedantic2.c: Use -pedantic-errors to obtain
	errors instead of warnings.
	* gcc.dg/cpp/extratokens.c: Use dg-warning instead of dg-error for
	a pedantic warning.
	* gcc.dg/cpp/arith-3.c: Likewise.
