+       * bootstrap: Remove workaround for problem I encountered with
+       gettext 0.14.1; it seems to be fixed now.
+
+2005-05-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * NEWS: Version 2.0a.
+
+       * src/files.c: Include "stdio-safer.h"; this fixes a typo in
+       the previous change.
+
+       Various maintainer cleanups.
+       * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
+       conftest*, for benefit of CVS commands run at the same time as
+       "configure".  Add build-aux, since "bootstrap" now creates it and
+       its subfiles.
+       * Makefile.cfg (move_if_change): Remove.
+       * Makefile.maint: Remove the update stuff; we now use "bootstrap".
+       (ftp-gnu, www-gnu, move_if_change, local_updates, update):
+       (po_repo, do-po-update, po-update, wget_files, get-targets):
+       (config.guess-url_prefix, config.sub-url_prefix):
+       (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
+       (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
+       ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
+       Remove.
+       * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
+       this is now the recommended name.
+       * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
+       depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
+       ylwrap.  These files now go into build-aux.
+       * config/move-if-change: Remove.
+       * config/prev-version.txt: Bump from 1.75 to 2.0.
+
+       * bootstrap: Add stdio-safer, unistd-safer modules.
+       Remove m4/glibc2.m4 (introduced by latest gnulib, but
+       we don't need it).
+       * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
+       fopen-safer.c, stdio-safer.h, unistd-safer.h.
+       * lib/subpipe.c: Include "unistd-safer.h".
+       (create_subpipe): Make sure all the newly-created
+       file descriptors are > 2, so that diagnostics don't
+       get sent down them (which might cause Bison to hang, in theory).
+       * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
+       * src/files.c (xfopen): Use fopen_safer, not fopen.
+
+       * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
+       yesterday's yacc.c fix.
+
+2005-05-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/glr.c, data/lalr1.cc: Update copyright date.
+
+       Fix a destructor bug reported by Wolfgang Spraul in
+       <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
+       * data/yacc.c (yyabortlab): Don't call destructor, and
+       don't set yychar to EMPTY.
+       (yyoverflowlab): Don't call destructor.
+       (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
+       * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
+       since we no longer output the message "discarding lookahead token
+       end of input ()".
+
+2005-05-20  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
+
+       * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
+       fix a small glitch in debugging output.
+       (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
+       after YY_SYMBOL_PRINT where needed.
+
+       (struct yyGLRState): Add some comments.
+       (struct yySemanticOption): Add some comments.
+       (union yyGLRStackItem): Add comment.
+
+       (yymergeOptionSets): Correct this to properly perform the union,
+       avoiding infinite reported by Michael Rosien.
+       Update comment.
+
+       * tests/glr-regression.at: Add test for GLR merging error reported
+       by M. Rosien.
