removed.
(libbison_a_SOURCES): Add unlocked-io.h. Avoid +=, a GNU make extension.
(bitsets_sources, additional_bitsets_sources, timevars_sources): New vars.
* src/lalr.h (LA, LArule): Don't export them: used with the
state_t.
* src/lalr.c (LA, LArule): Static.
* src/lalr.h, src/lalr.c (lalr_free): New.
* src/main.c (main): Call it.
* src/tables.c (pack_vector): Check whether loc is >= to the
table_size, not >.
(pack_tables): Don't free froms, tos, conflict_tos, and pos...
(tables_generate): do it, since that's also it which allocates
them.
Don't free LA and LArule, main does.
(Tracing): this new section, its former contents, and...
(Understanding): this new section.
* src/getargs.h, src/getargs.c (verbose_flag): Remove, replaced
by...
(report_flag): this.
Adjust all dependencies.
(report_args, report_types, report_argmatch): New.
(usage, getargs): Report/support -r, --report.
* src/options.h
(struct option_table_struct): Rename as..,
(struct option_table_s): this.
Rename the `set_flag' member to `flag' to match with getopt_long's
struct.
* src/options.c (option_table): Split verbose into an entry for
%verbose, and another for --verbose.
Support --report/-r, so remove -r from the obsolete --raw.
* src/print.c: Attach full item sets and lookaheads reports to
report_flag instead of trace_flag.
* lib/argmatch.h, lib/argmatch.c: New, from Fileutils 4.1.
Fileutils 4.1.5.
* configure.in: Invoke UTILS_FUNC_MKSTEMP.
* src/output.c (output_skeleton): Use mkstemp to create a real
temporary file.
Move the filling of `skeleton' and its muscle to...
(prepare): here.
(output): Move the definition of the prologue muscle to...
(prepare): here.
* src/system.h (DEFAULT_TMPDIR): New.
* 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.
New, stolen from the Fileutils 4.1.
* lib/Makefile.am (libbison_a_SOURCES): Adjust.
* configure.in: Check for the presence of memrchr, and of its
prototype.
* src/Makefile.am: Add parse-skel.c and scan-skel.c to BUILT_SOURCES, to ensure they are generated first.
* src/parse-skel.y: Use YYERROR_VERBOSE instead of %error-verbose to allow bootstrapping with bison 1.30x.
Throw away MS-DOS crap: we don't need getpid.
* configure.in: We don't need strndup. It was even causing
problems: because Flex includes the headers *before* us,
_GNU_SOURCE is not defined by config.h, and therefore strndup was
not visible.
* lib/xstrndup.c: New.
* src/scan-skel.l: Use it.
Be sure to initialize yylval.muscle member when scanning a MUSCLE.
* src/parse-skel.y: Use %directives instead of #defines.
Replace strchr if needed.
* src/system.h: Provide the protos of strchr, strspn and memchr if
missing.
* lib/strchr.c: New.
* src/reader.c (symbols_save): Use strchr.
(CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
Gettext doesn't compile cleanly, and dies with -Werror.
* src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
Include WARNING_CFLAGS here.
* lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
before being defined.
First arg is int, not unsigned.
* lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
(SIZE_MAX, UINT_MAX): New macros.
(quotearg_n_options): Abort if N is negative.
Avoid overflow check on hosts where size_t is 64 bits and int
is 32 bits, as overflow is impossible there.
Fix off-by-one typo that caused unnecessary reallocation.
* src/output.c (prepare): Add prefixed names.
(output_parser): Output semantic actions.
(output_parser): Fix bug on '%%line' directives.

function should now be in the skeletons.

(token_actions): Same for 'defact'.
(goto_actions): Same for 'defgoto'.
(output_base): Same for 'pact' and 'pgoto'.

copy_identifier rather than lex.
2001-08-16 Robert Anisko <robert.anisko@epita.fr>
* src/reader.c (copy_identifier): New.

* src/reader.c (parse_macro_decl): New function used to parse macro
declarations.
(copy_string2): Put the body of copy_string into this new function.
Add a parameter to let the caller choose whether he wants to copy the
string delimiters or not.
(copy_string): Be a simple call to copy_string2 with the last argument
bound to true.
2001-08-15 Robert Anisko <robert.anisko@epita.fr>
* src/output.c (output_parser): Replace most of the skeleton copy code
with something new. Skeletons are now processed character by character
rather than line by line, and Bison looks for '%%' macros. This is the
first step in making Bison's output process (a lot) more flexible.
