(yyreportSyntaxError): Use it to dequote most string literals.
* data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
with other skeletons. All uses changed.
(yytnameerr_): New function.
(yyreport_syntax_error): Use it to dequote most string literals.
* data/yacc.c (yytnamerr): New function.
(yyerrlab): Use it to decode most string literals.
* doc/bison.texinfo (Decl Summary, Calling Convention):
Clarify quoting convention of yytname.
* src/output.c (prepare_symbols): Quote all names. This undoes
the 2005-04-17 change, which is now accomplished (mostly) via
changes in the parsers as described above.
* tests/regression.at (Token definitions, Web2c Actions):
Undo most 2005-04-17 change here, too.
* NEWS: Document the behavior changes.
* data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
stack before failing, as the cleanup code will do it for us now.
* data/lalr1.cc (yyerrlab): Likewise.
* data/glr.c (yyparse): Pop everything off the stack before
freeing it, so that destructors get called properly.
* data/lalr1.cc (yyreturn): Likewise.
* data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
This is more consistent.
* doc/bison.texinfo (Destructor Decl): Mention more reasons
why destructors might be called. 1.875 -> 2.1.
(Destructor Decl, Decl Summary, Table of Symbols):
Some English-language cleanups for %destructor.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
Add output line for destructor of start symbol.
* tests/calc.at (AT_CHECK_CALC): Add one to line counts,
because of that same extra output line.
skeleton; a C++ expert needs to finish this. Remove debugging
msgids; there's little point to having them translated, since they
can be understood only by someone who can read the
(English-language) source code.
Generate runtime-po/bison-runtime.pot automatically, so that we
don't have to worry about garbage getting in that file. We'll
make sure after the next official release that old msgids don't
get lost. See
<http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
* runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
Now auto-generated.
* PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
Fix typos in explanations of the runtime file.
* bootstrap: Change gettext keyword from YYI18N to YY_.
Use standard Makefile.in.in in runtime-po, since we'll arrange
for backward-compatible bison-runtime.po files in a different way.
* data/glr.c (YY_): New macro, from yacc.c.
(yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
Translate messages intended for users.
(yyreportSyntaxError): Change "virtual memory" to "memory" to match
the wording in the other skeletons. We don't know that the memory
is virtual.
* data/lalr1.cc (YY_): Renamed from _. All uses changed.
Use same method that yacc.c uses.
Don't translate debugging messages.
(yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
it doesn't work (yet), and requires C++ expertise to fix.
* data/yacc.c (YY_): Renamed from YY18N. All uses changed.
Move defn to a more logical place, to be consistent with other
skeletons.
Don't translate debugging messages.
Don't assume line numbers fit in unsigned int; use unsigned long fmts.
* doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
* runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
Create runtime-po files automatically, if possible.
* configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
* data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
does not infringe on the user's name space.
(YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
* doc/bison.texinfo (Internationalization): Revamp the English
and Texinfo syntax a bit, to try to make it clearer.
(Bison Options, Option Cross Key): Mention --print-localedir.
* m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
YYENABLE_NLS. Quote a bit more.
* runtime-po/.cvsignore: New file.

* runtime-po/en@quot.header: Likewise.
* runtime-po/en@boldquot.header: Likewise.
* runtime-po/insert-header.sin: Likewise.
* runtime-po/remove-potcdate.sin: Likewise.
* runtime-po/Makevars: Likewise.
* runtime-po/LINGUAS: Likewise.
* runtime-po/de.po: Likewise; we will rely on the translation project
to maintain this, so "bootstrap" should get it.
* src/getarg.s (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
its value.
* src/main.c (main): Bind the bison-runtime domain, too.
* data/yacc.c: Include <libintl.h> when NLS is enabled.
(YYI18N): Renamed from _. Use dgettext when NLS is enabled.
* po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
* runtime-po: New directory.
* runtime-po/Makefile.in.in: New file, copied from po/, with modified
$(DOMAIN).pot-update rule, so that old messages are never dropped.
* runtime-po/Rules-quot: New file, copied from po/.
* runtime-po/quot.sed: Likewise.
* runtime-po/boldquot.sed: Likewise.
* runtime-po/en@quot.header: Likewise.
* runtime-po/en@boldquot.header: Likewise.
* runtime-po/insert-header.sin: Likewise.
* runtime-po/remove-potcdate.sin: Likewise.
* runtime-po/Makevars: New file.
* runtime-po/POTFILES.in: New file.

* doc/bison.texinfo (Bison Parser): Remove paragraph about _().
(Internationalization): New section.
* doc/bison.texinfo (Calc++): Add the extraction marks.
* examples/extexi: New, from the aborted GNU Programming 2E.
Separate the different paragraph of a file with empty lines.
* examples/Makefile: Use it to extract the whole calc++ example.
translate strings.
* data/yacc.c (_) [!defined _]: New macro.
All English strings wrapped inside this macro.
* doc/bison.texinfo (Bison Parser): Document _.
* po/POTFILES.in: Include src/parse-gram.c, since it now
includes translateable strings that parse-gram.y doesn't.
alloca function (when available) to extend the parser stack, due
to widespread problems in unchecked stack-overflow detection.
* data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
responsibility to set it to a positive value. This lets the user
specify a value that is not a preprocessor constant.
* data/yacc.c (YYMAXDEPTH): Likewise.
(YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
* doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
to be a compile-time constant. However, explain the constraints on it.
Also, explain the constraints on YYINITDEPTH.
(Table of Symbols): Explain that alloca is no longer the default.
Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
to 1.
"initial push" (corresponding to an hypothetical beginning-of-file).
And let lalr1.cc honor %initial-action.
* doc/bison.texinfo (Initial Action Decl): Clarify, and add an
example.
* data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
(Parser::Parser): Remove the ctor that used to initialize it.
(Parser::parse): Like in the other skeletons, issue the "starting
parse" message before any action.
Honor %initial-action.
Initialize the stacks with the lookahead.
* data/yacc.c: Let $$ and @$ in %initial-action designate the
look-ahead.
Push them in the stacks.
* tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
invoked, yydestruct the lookahead.
* tests/calc.at (Calculator $1): Update the expected lengths of
traces: there is an added line for the discarded lookahead.
* doc/bison.texinfo (Destructor Decl): Some rewording.
Define "discarded" symbols.
(declaration): Replace expected_conflicts with expected_sr_conflicts.
Add %expect-rr rule.

expected_conflicts.
(expected_rr_conflicts): Declare.

expected_conflicts.
(expected_rr_conflicts): Define.

for GLR parsers.
Use expected_sr_conflicts in place of expected_conflicts.
Warn if expected_rr_conflicts used in non-GLR parser.
* doc/bison.texinfo: Add documentation for %expect-rr.
English a bit. Fix fclose typo. Change "const char" to "char
const", and use ANSI C rather than K&R for "main". Suggest
YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
and suggest yy_switch_to_buffer.
