4d7aa45e75 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
as __STDC__, as IBM cc defines the former but not the latter.
* data/yacc.c (YYMODERN_C): New macro, which also looks at
__STDC_VERSION__.  Use it everywhere instead of looking at
__STDC__ and __cplusplus.

2f4f028d8b Undo the parts of the unlocked-I/O change that substituted
putc or puts for printf.  This might hurt performance a bit,
but some people prefer the printf style.
* data/c.m4 (yysymprint): Prefer printf to puts and putc.

fb9c0b3360 Use unlocked I/O for a minor performance improvement on hosts like
GNU/Linux and Solaris that support unlocked I/O.  The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

040984073a * NEWS: Version 2.0b.

the user's name space.  All uses changed to __attribute__
((__unused__)).

it's error-prone and "make maintainer-distcheck" rejects it.

Indent calls to "error" to pacify "make maintainer-distcheck",

30757c8c93 Add i18n support to the GLR skeleton. Partially fix the C++
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.

value of the result.

(error_range_): this location array.
This allows to replace code relying on the implementation of
locations by portable code.
* data/yacc.c (yylerrsp): Replace with...
(yyerror_range): this.
Every time a token is popped, update yyerror_range[0], to have an
accurate location for the error token.
* data/glr.c (YY_LOCATION_PRINT): New.
(yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
deference a pointer.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
report the location in %printers.
* src/scan-skel.l: Instead of abort, report error messages to ease
understanding skeleton scanning failures.

argument, an informative message.
Call YY_SYMBOL_PRINT.
Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
* data/lalr1.cc (destruct_): Likewise.
In addition, no longer depend on b4_yysymprint_generate and
b4_yydestruct_generate to generate these functions, do it "by
hand".

it to YYEMPTY etc.).
(yydestruct): Replace with a b4_yydestruct_generate invocation.
(b4_symbol_actions): Remove.
