4233
4234         * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
4235         RID_LAST_PQ.  Move RID_FIRST_PQ down with the other FIRST/LAST
4236         enumerators.
4237         (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
4238
4239         * c-parse.in (OBJC_STRING): Kill.
4240         (objc_string): Decompose to [objc_string] '@' STRING.
4241         (reswords): Take the leading '@' off all the Objective C keywords.
4242         (objc_rid_sans_at): Kill.
4243         (init_reswords): Don't initialize it.
4244         (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
4245         (_yylex): Kill reconsider label.  Look ahead one token after
4246         an '@'; if we get an identifier, check whether it's an
4247         Objective C @-keyword.  If so, return the keyword.  Otherwise,
4248         put back the token and return the '@' as a terminal.
4249
4250         * cpplib.c (lex_macro_node): Remove unnecessary check for
4251         leading '@' on identifier.  Clarify control flow and commentary.
