+       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).

+
+       * 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.

+       * 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.

        The gettext version checking is causing more trouble than it's
        curing; remove it.  Problem reported by Paul Hilfinger.
