13396 LIBRARY_PATH from the environment.
13398 2001-07-01 Zack Weinberg <zackw@stanford.edu>
13400 * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
13401 RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
13403 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
13405 * c-parse.in (OBJC_STRING): Kill.
13406 (objc_string): Decompose to [objc_string] '@' STRING.
13407 (reswords): Take the leading '@' off all the Objective C keywords.
13408 (objc_rid_sans_at): Kill.

13410 (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
13411 (_yylex): Kill reconsider label. Look ahead one token after
13412 an '@'; if we get an identifier, check whether it's an
13413 Objective C @-keyword. If so, return the keyword. Otherwise,
13414 put back the token and return the '@' as a terminal.
13416 * cpplib.c (lex_macro_node): Remove unnecessary check for
13417 leading '@' on identifier. Clarify control flow and commentary.
