+2000-10-02 Akim Demaille <akim@epita.fr>

+
+ The location tracking mechanism is precious for parse error
+ messages. Nevertheless, it is enabled only when `@n' is used in
+ the grammar, which is a different issue (you can use it in error
+ message, but not in the grammar per se). Therefore, there should
+ be another means to enable it.
+
+ * src/getargs.c (getargs): Support `--locations'.
+ (usage): Report it.
+ * src/getargs.h (locationsflag): Export it.
+ * src/lex.c (percent_table): Support `%locations'.
+ * src/reader.c (yylsp_needed): Remove this variable, now replaced
+ with `locationsflag'.
+ * doc/bison.texinfo: Document `--locations' and `%locations'.
+ Sort the options.
+ * tests/calc.m4: Test it.
+
+ For regularity of the names, replace each
+ (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
+ (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
+ In addition replace each `flag' with `_flag'.

+ Also test parse error messages, including with YYERROR_VERBOSE.
+
+ * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
+ associative).
+ Use it to check the computations.
+ Use it to check `nonassoc' is honored.
+ (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
+ `--yyerror-verbose'.
+ (_AT_CHECK_CALC): Adjust to this option.
+ (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.

+
+ Test also `--verbose', `--defines' and `--name-prefix'. Testing
+ the latter demonstrates a flaw in the handling of non debugging
+ parsers introduced by myself on 2000-03-16: `#define yydebug 0'
+ was used in order to simplify:
+
+ #if YYDEBUG
+ if (yydebug)
+ {
+ ...
+ }
+ #endif
+
+ into
+
+ if (yydebug)
+ {
+ ...
+ }
+
+ unfortunately this leads to a CPP conflict when
+ `--name-prefix=foo' is used since it produces `#define yydebug
+ foodebug'.
+
+ * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
+ (YYDPRINTF): New macro.
+ Spread its use.
+ * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
+ the bison options.
+ Also test `--verbose', `--defines' and `--name-prefix'.

+ Improve the readability of the produced parsers.
+
+ * src/bison.s1: Formatting changes.
+ Improve the comment related to the `$' mark.
+ (yydefault): Don't fall through to `yyresume': `goto' there.
+ * src/output.c (output_parser): When the `$' is met, skip the end
+ of its line.
+ New variable, `number_of_dollar_signs', to check there's exactly
+ one `$' in the parser skeleton.
