+       * getdate.y: Use Bison 1.875 features, and some minor
+       code cleanups.  This change does not affect semantics.
+       Don't include <stdlib.h>; no longer needed.
+       Don't include unlocked-io.h; only the "#if TEST" code uses
+       stdio, and performance isn't crucial there.
+       (PC, YYLEX_PARAM, YYPARSE_PARAM): Remove; replaced by
+       Bison 1.875 features as described below.
+       All uses of "PC." replaced by "pc->".
+       (YYSTYPE): Add a forward declaration.
+       (yylex, yyerror): Use full prototypes in forward decls.
+       Use "%pure-parser" rather than obsolescent "%pure_parser".
+       Use %parse-param and %lex-param instead of obsolescent
+       YYPARSE_PARAM and YYLEX_PARAM.
+       (meridian_table, month_and_day_table, time_units_table,
+       relative_time_table, time_zone_table, military_table,
+       lookup_zone, lookup_word, get_date):
+       Use NULL instead of 0 where appropriate.
+       (to_hour): Avoid abort (), to avoid a dependency on
+       stdlib.h.
+       (yyerror, yylex): Now accepts parser_control * arg.
+       (main) [TEST]: Use '\0' rather than 0 for char.
+

        * getpagesize.c (getpagesize): Don't assume <sys/param.h> exists.
