6571 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
6573 * c-parse.in (OBJC_STRING): Kill.
6574 (objc_string): Decompose to [objc_string] '@' STRING.
6575 (reswords): Take the leading '@' off all the Objective C keywords.
6576 (objc_rid_sans_at): Kill.
6577 (init_reswords): Don't initialize it.
6578 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
6579 (_yylex): Kill reconsider label. Look ahead one token after
6580 an '@'; if we get an identifier, check whether it's an
6581 Objective C @-keyword. If so, return the keyword. Otherwise,
6582 put back the token and return the '@' as a terminal.
6584 * cpplib.c (lex_macro_node): Remove unnecessary check for
6585 leading '@' on identifier. Clarify control flow and commentary.
