c-opts.c (c_common_parse_file): Unconditionally give a warning, suitable for the language, if set_yydebug is true.

	* c-opts.c (c_common_parse_file): Unconditionally give a warning,
	suitable for the language, if set_yydebug is true.
	* c-pragma.h: Define enum pragma_omp_clause here.  Don't define
	YYDEBUG or declare yydebug.
	* c-parser.c (yydebug, enum pragma_omp_clause): Delete.
	* cp/parser.c: Likewise.
