4266 * c-parse.in (OBJC_STRING): Kill.
4267 (objc_string): Decompose to [objc_string] '@' STRING.
4268 (reswords): Take the leading '@' off all the Objective C keywords.
4269 (objc_rid_sans_at): Kill.
4270 (init_reswords): Don't initialize it.
4271 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
4272 (_yylex): Kill reconsider label. Look ahead one token after
4273 an '@'; if we get an identifier, check whether it's an
4274 Objective C @-keyword. If so, return the keyword. Otherwise,
4275 put back the token and return the '@' as a terminal.
4277 * cpplib.c (lex_macro_node): Remove unnecessary check for
4278 leading '@' on identifier. Clarify control flow and commentary.
