+ Use type char, not unsigned int, when declaring an array of char;

+ C++ compiler. (trivial change)
+
+2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Spent a few hours checking out which prerequisite versions the
+ current sources actually require. I went all the way back to
+ Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+ a seemingly endless set of combinations of versions more recent
+ than that. The bottom line is that the current sources require
+ fairly recent versions of the build tools, and it'll be some work
+ to change this.
+ * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+ (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+ (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+ Add comments explaining why those particular versions are
+ currently needed.
+
+ * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+ in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
+ <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+ * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+ (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+ 0.11.5. Suggested by Bruno Haible.
+ * bootstrap: Remove gettext version checking.
+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim
+ Van Holder.
+
+2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention GNU m4 1.4 bugs and Akim's patched version.
+ * README-alpha: Don't tell people not to package this.
+
+ * bootstrap: Don't assume $(...) works; use `...` instead.
+ Problem reported by Paul Hilfinger. Also, diagnose non-GNU
+ gettext better.
+
+ * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
+ put into the -d output file, and mention what to do if YYSTYPE is
+ defined as a macro.
+
+2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo change made earlier today: it caused autopoint to not bring
+ in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
+ autopoint's.
+
+ * bootstrap: Check that gettext version matches what's in
+ configure.ac. Warn users to ignore robots.txt ERROR 404.
+ * bootstrap: Undo today's earlier change (logged below).
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
+
+ The gettext version checking is causing more trouble than it's
+ curing; remove it. Problem reported by Paul Hilfinger.
+
+ * bootstrap: Issue a warning that one can expect a message
+ 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.

+
+ * configure.ac (AC_INIT): Update to 1.875e.

+
+ * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
+ -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
+ lalr1.cc runs afoul of the first, and the last two are no longer
+ supported by GCC 3.4.0.
+ * README: Mention GNU m4 1.4 or later; mention m4 patches.
+ * HACKING: Use ./bootstrap, not "make update" to import foreign files.
+
