(grammar_current_rule_symbol_append)
(grammar_current_rule_action_append): Export.
* src/parse-gram.y (symbol_list_new, symbol_list_symbol_append_
(symbol_list_action_append): Remove.
Hook the routines from reader.
* src/scan-gram.l: In INITIAL, characters and strings are tokens.
* src/system.h (ATTRIBUTE_NORETURN, ATTRIBUTE_UNUSED): Now.
* src/reader.c (read_declarations): Remove, unused.
* src/parse-gram.y: Handle the epilogue.
* src/reader.h, src/reader.c (gram_start_symbol_set): Rename as...
(grammar_start_symbol_set): this.
* src/scan-gram.l: Be sure to ``use'' yycontrol to keep GCC quiet.
* src/reader.c (readgram): Remove, unused.
(reader): Adjust to insert eoftoken and axiom where appropriate.
* src/reader.c (copy_dollar): Replace with...
* src/scan-gram.h (handle_dollar): this.

* src/reader.c (copy_at): Replace with...
* src/scan-gram.h (handle_at): this.
* src/complain.h, src/complain.c (warn_at, complain_at, fatal_at):
New.

time being.
* src/reader.h, src/reader.c (grammar_rule_end): New.
* src/parse.y (current_type, current_class): New.
Implement `%nterm', `%token' support.
Merge `%term' into `%token'.
(string_as_id): New.
* src/symtab.h, src/symtab.c (symbol_make_alias): Don't pass the
type name.
* src/parse-gram.y: Be sure to handle properly the beginning of
rules.
* src/parse-gram.y: Handle %type.
* src/reader.c (grammar_rule_end): Call grammar_current_rule_check.
* src/parse-gram.y: More directives support.
* src/options.c: No longer handle source directives.
* src/parse-gram.y: Fix %output.

Use the prologue locations.
* src/reader.c (parse_union_decl): Remove.
* src/reader.h, src/reader.c (epilogue_set): New.
* src/parse-gram.y: Use it.
* data/bison.simple, data/bison.c++: b4_stype is now either not
defined, then default to int, or to the contents of %union,
without `union' itself.
Adjust.
* src/muscle_tab.c (muscle_init): Don't predefine `stype'.
* src/output.c (actions_output): Don't output braces, as they are
already handled by the scanner.
* src/scan-gram.l (SC_CHARACTER): Set the user_token_number of
characters to themselves.
* tests/reduce.at (Reduced Automaton): End the grammars with %% so
that the epilogue has a proper #line.

a terminal.
* src/scan-gram.l (SC_BRACED_CODE): Catch strings and characters.
* tests/calc.at: Do not use `%token "foo"' as it makes not sense
at all to define terminals that cannot be emitted.
* src/scan-gram.l: Escape M4 characters.
* src/scan-gram.l: Working properly with escapes in user
strings/characters.
* tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR)
(AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'
grammar.
Use more modest sizes, as for the time being the parser does not
release memory, and therefore the process swallows a huge amount
of memory.
* tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the
stricter %token grammar.
* src/symtab.h (associativity): Add `undef_assoc'.
(symbol_precedence_set): Do nothing when passed an undef_assoc.
* src/symtab.c (symbol_check_alias_consistence): Adjust.
* tests/regression.at (Invalid %directive): Remove, as it is now
meaningless.

(Token definitions): The new grammar doesn't allow too many
eccentricities.
* src/lex.h, src/lex.c: Remove.
* src/reader.c (lastprec, skip_to_char, read_signed_integer)
(copy_character, copy_string2, copy_string, copy_identifier)
(copy_comment, parse_token_decl, parse_type_decl, parse_assoc_decl)
(parse_muscle_decl, parse_dquoted_param, parse_skel_decl)

comma.

be2a1a68ef Give a try to M4 as a back end.
* lib/readpipe.c: New, from wdiff.
* src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
BISON_HAIRY.
* src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
specific values.  Now it is m4 that performs the lookup.
* src/parse-skel.y: Remove.
* src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
* src/output.c (actions_output, guards_output)
(token_definitions_output): No longer keeps track of the output
line number, hence remove the second argument.
(guards_output): Check against the guard member of a rule, not the
action member.
Adjust callers.
(output_skeleton): Don't look for the skeleton location, let m4 do
that.
Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
file will be used.
Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
(prepare): Given that for the time being changesyntax is not
usable in M4, rename the muscles using `-' to `_'.
Define `defines_flag', `output_parser_name' and `output_header_name'.
* src/output.h (actions_output, guards_output)
(token_definitions_output): Adjust prototypes.
* src/scan-skel.l: Instead of scanning the skeletons, it now
processes the output of m4: `__oline__' and `#output'.
* data/bison.simple: Adjust to be used by M4(sugar).
* tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
to date.
* tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.

091e20bbee Don't store the token defs in a muscle, just be ready to output it
on command.  Now possible via `symbols'.  Fixes a memory leak.
* src/output.c (token_definitions_output): New.
(output_parser, header_output): Use it.
* src/reader.c (symbols_save): Remove.

78af9bbcd3 * src/getargs.h: Don't declare `spec_name_prefix' and
`spec_file_prefix', declared by src/files.h.
* src/files.c, src/files.h: Default for spec_name_prefix is "yy".
* src/muscle_tab.c (muscle_init): Default prefix to NULL.
* src/output.c (prepare): Adjust.
* src/reader.c (symbols_output): Likewise.
* src/vmsgetargs.c: Vaguely adjust, but who cares?

bdef2a413a * src/muscle_tab.c (muscle_init): NULL is a better default than
`"0"'.

0edad74997 * src/options.c (OPTN, DRTV, BOTH): New.
(option_table): Use them.
* src/muscle_tab.c: Don't include xalloc.h and string.h: that's
the job of system.h.
* src/options.c: Don't include stdio.h and xalloc.h for the same
reasons.

a870c5670e Clean up GCC warnings.
* src/reader.c (copy_action): `buf' is not used.
(parse_skel_decl): Be static.
* src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.

(hash_delete_at): Return const void *.
Adjust casts to preserve the const.
