+2002-11-20  Paul Eggert  <eggert@twinsun.com>
+
+       * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
+
+2002-11-20  Paul Eggert  <eggert@twinsun.com>
+       
+       Avoid use of <assert.h>, as the GNU Coding Standards hint that one
+       should use `if (! x) abort ();' rather than `assert (x);', and
+       anyway it's one less thing to worry about configuring.
+
+       * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
+       and replace all instances of assert with abort.
+       * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
+       * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.

+       state_reduction_find): Likewise.
+       * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
+       symbol_pack): Likewise.
+       * src/tables.c (conflict_row, pack_vector): Likewise.
+       * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

+       get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,

+       rather than assert.
+       * src/tables.c (tables_generate): Likewise.
+
+       * src/struniq.c (struniq_assert): Now returns void, and aborts
+       if the assertion is false.
+       (struniq_assert_p): Remove.
+       * src/struniq.h: Likewise.
+
+2002-11-18  Paul Eggert  <eggert@twinsun.com>
+
+       * data/glr.c (yygetLRActions): Replace `yyindex' with
+       `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
+       This fixes the regression with Sun ONE Studio 7 cc that I reported in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.
+

+
+2002-11-17  Paul Eggert  <eggert@twinsun.com>
+

+
+       * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
+       not define to {}, since this breaks the common use of `YYDPRINTF
+       ((...));' if a single statement is desired (e.g. before `else').
+       Work around GCC warnings by surrounding corresponding calls with
+       {} if needed.
+       (yyhasResolvedValue): Remove unused function.
+       (yymergeOptionSets, yyresolvStack): Use `continue;' for empty

+       YYDPRINT here.
+       (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
+       state reached after the reduction/recovery, since...
+       (yyparse, yyprocessOneStack): Report the state we are entering in.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+       * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
+       Add support for --trace=skeleton.
+       * src/scan-skel.l: %option debug.
+       Scan strings of non-@ or \n instead of character by character.
+       (scan_skel): Handle trace_skeleton.
+       (QPUTS): New.
+       (@output_parser_name@, @output_header_name@): ``Restore'' their
+       support (used to be M4 macros).
+       * data/yacc.c: Quote larger chunks, a la glr.c.
+       * data/lalr1.cc: Likewise.
+       The header guards are no longer available, so use some other
+       string than `YYLSP_NEEDED'.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+       Make the ``Printers and Destructors'' test more verbose, taking
+       `yacc.c''s behavior as (possibly wrong) reference.
+
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
+       instead of fprint on stdout.
+       Set and report the last_line of the symbols.
+       Consistently display values and locations.
+
+2002-11-16  Paul Eggert  <eggert@twinsun.com>

+
+       * tests/actions.at (Actions after errors): New test case.

+       src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
+       tests/action.at, tests/calc.at, tests/conflicts.at,
+       tests/cxx-type.at, tests/regression.at:
+       "parse error" -> "syntax error" for POSIX compatibility.
+       "parsing stack overflow..." -> "parser stack overflow" so
+       that code matches Bison documentation.
+
+2002-11-15  Akim Demaille  <akim@epita.fr>
+
+       * src/parse-gram.y (declaration): Have %parse-param and %lex-param
+       take two BRACED_CODE, not two string_content.
+       Free the scanner's obstack when we are done.
+       (code_content): New.
+       * tests/calc.at: Adjust.
+       * doc/bison.texinfo: Adjust.
+       Also, make sure to include the `,' for these declarations.
+
+2002-11-15  Tim Van Holder  <tim.van.holder@pandora.be>
+
+       * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
+       definition; avoids potential autoreconf problems.
+
+2002-11-15  Akim Demaille  <akim@epita.fr>
+
+       Always check the value returned by yyparse.
+

+       returned by yyparse.
+       (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
+       Adjust calls.
+       * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
+       returned by yyparse.

+
+2002-11-14  Paul Eggert  <eggert@twinsun.com>
+
+       * src/output.c (output_skeleton): Call xfopen instead of
+       duplicating xfopen's body.
+
+       Fix bugs reported by Nelson H. F. Beebe in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
+
+       * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
+       "$CC -E foo.h" is allowed, as this doesn't work with the Portland
+       Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
+       file twice in the grammar, as an extra check.
+
+       * tests/input.at (Torturing the Scanner): Surround the
+       backslash-newline tests with "#if 0", to make it less likely that
+       we'll run into compiler bugs.  Bring back solitary \ inside
+       comment, but add a closing comment to work around HP C bug.  Don't
+       test backslash-newline in C character constant.  This should fix
+       the input.at bug reported by Nelson H. F. Beebe in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.

+
+       * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
+       status of the compiler.
+       Calling `exit 1' is no longer needed.
+       Reported by Nelson H. F. Beebe.
+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+       * tests/atlocal.in (CPPFLAGS): We have config.h.

+       * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
+       * tests/regression.at, tests/torture.at: Use them for all the
+       grammars that are to be compiled.
+       * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
+       * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
+       * doc/bison.texinfo (GLR Parsers): Document `inline'.
+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+       * doc/bison.texinfo: Various formatting changes (alignments in
+       samples, additional @group/@end group, GCS in samples.
+       Use @deffn instead of simple @table to define the directives,
+       macros, variables etc.
+
+2002-11-13  Paul Eggert  <eggert@twinsun.com>
+
+       Fix some bugs reported by Albert Chin-A-Young in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
+
+       * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
+       -o c"; the HP C compiler chatters during compilation.
+       Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
+       * tests/headers.at (export YYLTYPE): Likewise.
+
+       * tests/input.at (Torturing the Scanner): Remove lines containing
+       solitary backslashes, as they tickle a bug in the HP C compiler.
+
+       * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
+       comments, since they're not portable.  Use GNU coding style.

+
+       Version 1.75b.
+
+       * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
+       (yyglrReduce): Return yyok, not 0.
+       This should avoid the enumerated-type warnings reported
+       by Nelson H.F. Beebe in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.

+       to avoid shadowing warnings by GCC.
+
+       * data/glr.c (inline): Remove #define.  It's the user's
+       responsibility to #define it away, just like 'const'.
+       This fixes one of the bugs reported by Nelson H.F. Beebe in

+
+       * Makefile.maint (po-check): Scan .l and .y files instead of the
+       .c and the .h files that they generate.  This fixes the bug
+       reported by Tim Van Holder in:
+       <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
+       Look for N_ as well as for _.  Try to avoid matching #define for
+       N_ and _.
+       * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
+       src/system.h.  Add src/parse-gram.y, src/scan-gram.l.
+       * src/scan-gram.l: Revamp regular expressions so that " and '
+       do not confuse xgettext.
+
+       * src/struniq.h (struniq_new): Do not declare the return type
+       to be 'const'; this violates the C standard.
+       * src/struniq.c (struniq_new): Likewise.
+
+2002-11-12  Albert Chin-A-Young <china@thewrittenword.com>
+
+       * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
+       duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
+       linker.

+       locations.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
+       not yyvalue.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
+       Use it to test the GLR parser.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
+       defines it.
+       * data/glr.c (yystos): New.
+       (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
+       (YYDSYMPRINT): New.

+       (b4_yydestruct_generate): Likewise.
+       * tests/cations.at (Printers and Destructors): Use Bison directives

+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
+       * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
+       Don't work on yychar (i.e., do set it to YYEMPTY, don't match
+       it against YYEMPTY and so forth), work on yytoken (i.e., set
+       it to YYEMPTY etc.).
