3819 * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
3820 RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
3822 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
3824 * c-parse.in (OBJC_STRING): Kill.
3825 (objc_string): Decompose to [objc_string] '@' STRING.
3826 (reswords): Take the leading '@' off all the Objective C keywords.
3827 (objc_rid_sans_at): Kill.
3828 (init_reswords): Don't initialize it.
3829 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
3830 (_yylex): Kill reconsider label. Look ahead one token after
3831 an '@'; if we get an identifier, check whether it's an
3832 Objective C @-keyword. If so, return the keyword. Otherwise,
3833 put back the token and return the '@' as a terminal.
3835 * cpplib.c (lex_macro_node): Remove unnecessary check for
3836 leading '@' on identifier. Clarify control flow and commentary.
