4240
4241         * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
4242         RID_LAST_PQ.  Move RID_FIRST_PQ down with the other FIRST/LAST
4243         enumerators.
4244         (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
4245
4246         * c-parse.in (OBJC_STRING): Kill.
4247         (objc_string): Decompose to [objc_string] '@' STRING.
4248         (reswords): Take the leading '@' off all the Objective C keywords.
4249         (objc_rid_sans_at): Kill.
4250         (init_reswords): Don't initialize it.
4251         (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
4252         (_yylex): Kill reconsider label.  Look ahead one token after
4253         an '@'; if we get an identifier, check whether it's an
4254         Objective C @-keyword.  If so, return the keyword.  Otherwise,
4255         put back the token and return the '@' as a terminal.
4256
4257         * cpplib.c (lex_macro_node): Remove unnecessary check for
4258         leading '@' on identifier.  Clarify control flow and commentary.
