11121 * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
11122 RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
11124 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
11126 * c-parse.in (OBJC_STRING): Kill.
11127 (objc_string): Decompose to [objc_string] '@' STRING.
11128 (reswords): Take the leading '@' off all the Objective C keywords.
11129 (objc_rid_sans_at): Kill.
11130 (init_reswords): Don't initialize it.
11131 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
11132 (_yylex): Kill reconsider label. Look ahead one token after
11133 an '@'; if we get an identifier, check whether it's an
11134 Objective C @-keyword. If so, return the keyword. Otherwise,
11135 put back the token and return the '@' as a terminal.
11137 * cpplib.c (lex_macro_node): Remove unnecessary check for
11138 leading '@' on identifier. Clarify control flow and commentary.
