	* c-common.h (enum rid): Add RID_CXX_COMPAT_WARN.
	(struct c_common_resword): Define.
	(D_CONLY, D_CXXONLY, D_C99, D_CXX0X, D_EXT, D_EXT89): Define.
	(D_ASM, D_OBJC, D_CXX_OBJC, D_CXXWARN): Define.
	(c_common_reswords, num_c_common_reswords): Declare.
	* c-common.c (c_common_reswords): New global const array.
	(num_c_common_reswords): New const int.
	* c-parser.c (struct resword, reswords): Don't define.
	(D_C89, D_EXT, D_EXT89, D_OBJC): Don't define.
	(c_parse_init): Clarify mask code.  Use c_common_reswords rather
	than reswords.  If warning about C++ keywords, give them a special
	RID code.
	(c_lex_one_token): Warn about C++ keywords.  Call
	objc_is_reserved_word rather than OBJC_IS_AT_KEYWORD.
	(c_parser_external_declaration): Look for RID_xxx rather than
	RID_AT_xxx, for ObjC++ keywords which are also C++ keywords.
	(c_parser_statement_after_labels): Likewise.
	(c_parser_objc_class_instance_variables): Likewise.
	(c_parser_objc_class_declaration): Likewise.
	(c_parser_objc_try_catch_statement): Likewise.
	* c-decl.c (c_print_identifier): Ignore RID_CXX_COMPAT_WARN.
	(declspecs_add_type): Likewise.
cp/:
	* lex.c (struct resword, reswords): Don't define.
	(D_EXT, D_ASM, D_OBJC, D_CXX0X): Don't define.
	(init_reswords): Clarify mask code.  Use c_common_reswords rather
	than reswords.
objc/:
	* objc-act.c (objc_is_reserved_word): Always check for RID_CLASS,
	etc., not just when OBJCPLUS is defined.
testsuite/:
	* gcc.dg/Wcxx-compat-2.c: New test.
