+
+       Prototype support of %lex-param and %parse-param.
+
+       * src/parse-gram.y: Add the definition of the %lex-param and
+       %parse-param tokens, plus their rules.
+       Drop the `_' version of %glr-parser.
+       Add the "," token.
+       * src/scan-gram.l (INITIAL): Scan them.
+       * src/muscle_tab.c: Comment changes.
+       (muscle_insert, muscle_find): Rename `pair' as `probe'.
+       * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
+       (muscle_entry_s): The `value' member is no longer const.
+       Adjust all dependencies.
+       * src/muscle_tab.c (muscle_init): Adjust: use
+       MUSCLE_INSERT_STRING.
+       Initialize the obstack earlier.
+       * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
+       (muscle_pair_list_grow): New.
+       * data/c.m4 (b4_c_function_call, b4_c_args): New.
+       * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
+       * tests/calc.at: Use %locations, not --locations.
+       (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
+
+2002-10-19  Akim Demaille  <akim@epita.fr>
+
+       * src/getargs.c (usage): Take status as argument and exit
+       accordingly.
+       Report the traditional `Try ... --help' message when status != 0.
+       (usage, version): Don't take a FILE * as arg, it is pointless.
+       (getargs): When there is an incorrect number of arguments, make it
+       an error, and report it GNUlically thanks to `usage ()'.

+
+       * data/glr.c (yyreportParseError): Don't assume that sprintf
+       yields the length of the printed string, as this is not true
+       on SunOS 4.1.4.  Reported by Peter Klein.
+
+       * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
+       * tests/conflicts.at (%nonassoc and eof): Likewise.
+       Fixes SunOS 4.1.4 test failure reported by Peter Klein.
+
+2002-10-17  Akim Demaille  <akim@epita.fr>
+
+       * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
+       * src/getargs.c (trace_types, trace_args): Adjust.
+       * src/reader.c (grammar_current_rule_prec_set)
+       (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
+       Standardize error messages.
+       And s/@prec/%prec/!
+       (reader): Use trace_flag to enable scanner/parser debugging,
+       instead of an adhoc scheme.
+       * src/scan-gram.l: Remove trailing debugging code.
