+ yysyntax_error: improve invocation readability.
+ * data/yacc.c (yyparse, yypush_parse): For yysyntax_error
+ invocation, get rid of the while loop, which is misleading
+ because there are really at most two iterations.
+
+2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
+
+ * ChangeLog: Correct some errors in previous entries.
+
+2010-10-17 Joel E. Denny <joeldenny@joeldenny.org>
+
+ maint: re-anchor all .gitignore entries.
+ * bootstrap: Copy from gnulib's latest for the fix to
+ automatically anchor entries it constructs.
+ * gnulib: Update to latest just so it has the same bootstrap.
+ * .gitignore, build-aux/.gitignore, doc/.gitignore:
+ * lib/.gitignore, m4/.gitignore, po/.gitignore:
+ * runtime-po/.gitignore: Re-anchor all entries.

+2010-10-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix portability problem on OpenBSD 4.7.
+
+ Jim Meyering reported this in
+ <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
+ * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
+ not _STDLIB_H. EXIT_SUCCESS has been defined by the standard
+ for quite some time.
+ * src/parse-gram.c, src/parse-gram.h: Regenerate.
+ * tests/regression.at: Tamper with the renamed witness.
+
+ Adjust to recent changes to gnulib bootstrap.
+
+ * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
+ * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
+ * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
+ * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
+ anymore and don't know of anybody else who does. If someone needs
+ these files, they can resurrect them.
+ * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
+ * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
+ Omit leading '/', since bootstrap omits it.
+ Adjust file names to match current contents better.
+ * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
+ installed just for us.
+ * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
+ glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
+ needed somehow. Don't have time to look into why.
+ (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
+ the GNU malloc behavior, where malloc (0) != NULL unless we're
+ out of storage? If not, we can omit malloc-gnu; but for now I left
+ it in to be safe.
+ (vc_ignore): Remove.
+ (gnulib_mk_hook): New function.
+ * README-hacking: Renamed from HACKING, since gnulib bootstrap now
+ uses that convention.
+
+2010-09-09 Paul Hilfinger <hilfinger@cs.berkeley.edu>
+
+ * data/glr.c (yySymbol): Define as int to avoid compiler warnings about
+ possible change of value.
