12403 * tlink.c (recompile_files): Remove COMPILER_PATH and
12404 LIBRARY_PATH from the environment.
12406 2001-07-01 Zack Weinberg <zackw@stanford.edu>
12408 * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
12409 RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
12411 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
12413 * c-parse.in (OBJC_STRING): Kill.
12414 (objc_string): Decompose to [objc_string] '@' STRING.
12415 (reswords): Take the leading '@' off all the Objective C keywords.
12416 (objc_rid_sans_at): Kill.

12418 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
12419 (_yylex): Kill reconsider label. Look ahead one token after
12420 an '@'; if we get an identifier, check whether it's an
12421 Objective C @-keyword. If so, return the keyword. Otherwise,
12422 put back the token and return the '@' as a terminal.
12424 * cpplib.c (lex_macro_node): Remove unnecessary check for
12425 leading '@' on identifier. Clarify control flow and commentary.
