* maint: rely on Automake for parsers.Akim Demaille2012-02-151-6/+6
| | | | | | | | | | | | | * Makefile.am (AM_YFLAGS): Automake looks for "-d" alone. Move other options in here. (BISON): New. (YACC): Use it. (bison_SOURCES): Now that automake can see `-d' in AM_YFLAGS, we can rely on it to compile and ship the parser header files. Based on commit 737406a32c201471699bfa0843d1f432f3ec29ab and commit 3d6ca339083c278d907c9f030f4ba6bc5ecb07f2.

Use quotearg as often as possible instead of leaving the choice of the quotes to the translators. Use shorter messages.

* do not ignore errors like ENOSPC,EIO when writing to stdoutJim Meyering2012-01-314-13/+22
| | | | | | | | | | | | | | | | | | | | | | | | Standard output was never explicitly closed, so we could not detect failure. Thus, bison would ignore the errors of writing to a full file system and getting an I/O error on write, but only for standard output, e.g., for --print-localedir, --print-datadir, --help and some verbose output. Now, "bison --print-datadir > /dev/full" reports the write failure: bison: write error: No space left on device Before, it would exit 0 with no diagnostic, implying success. This is not an issue for "--output=-" or the other FILE-accepting command-line options, because unlike most other GNU programs, an output file argument of "-" is treated as the literal "./-", rather than standard output. * bootstrap.conf (gnulib_modules): Add closeout. * src/main.c: Include "closeout.h". Use atexit to ensure we close stdout. * .gitignore: Ignore new files pulled in via gnulib-tool. (cherry picked from commit acb5895680611f8beb497b41694d9686f2932c50) Conflicts: m4/.gitignore

| | | | | | | | * tests/regression.at (parse-gram.y: LALR = IELR): Port to Solaris 10, where "diff -u X X" outputs "No differences encountered" instead of outputting nothing. Reported by Tomohiro Suzuki in <http://lists.gnu.org/archive/html/bug-bison/2012-01/msg00101.html>. (cherry picked from commit 071ca141ec7987a5eca782227ce70db434a206ab)
* build: avoid possibly-replaced fprintf in liby-source, yyerror.cJim Meyering2012-01-253-3/+6
| | | | | | | | | | | | * lib/yyerror.c (yyerror): Use fputs and fputc rather than fprintf with a mere "%s\n" format. Always return 0 now, on the assumption that the return value was never used anyway. Don't include <config.h> after all. This avoids a problem reported by Thiru Ramakrishnan in http://lists.gnu.org/archive/html/help-bison/2011-11/msg00000.html * cfg.mk: Exempt lib/yyerror.c from the sc_require_config_h_first test. * THANKS: Update.

* quote consistently and make tests pass with new quoting from gnulibJim Meyering2012-01-2310-182/+207
| | | | | | | | | | | | | | | | | | | | | | | | | Updating to gnulib pulled in new quote and quotarg modules, by which quoting is now done like 'this' rather than `this'. That change induces many "make check" test failures.

| | | | | | | | | | | | | | | | | | | Updating to the latest bootstrap from gnulib involves more of a change than usual, and updating to the latest gnulib would involve its own set of challenges with the upcoming quoting changes, so we update bootstrap manually and separately. * bootstrap: Update from gnulib. * lib/Makefile.am: Initialize more variables to empty, so that gnulib.mk can append to them with "+=". * bootstrap.conf (gnulib_mk_hook): Remove.
