| That diff contains the following changes:
| 
| * Install a shell script called "yacc" that looks like this:
| 
|       #!/bin/sh
|       exec bison -y "$@"
| 
|   POSIX 1003.1-2001 requires that there be a "yacc" command, and I
|   think it's reasonable for Bison to install a shell script like this.
|   However, it might break sites that install both Bison and Yacc
|   (e.g. Berkeley Yacc) so I'm tempted to say that this should be
|   deferred to a major release, not a minor bugfix update.

Why not, indeed.

| * Patch a typo in po/es.po that could lead to a core dump.  I
|   installed this on the Bison maintenance branch (it wasn't needed on
|   the development branch, I'm not sure why).

Because I don't update it from the TP.  I regularly update 1.3x from
the TP, and regularly fix that problem.  I don't understand how it
escaped this time, given that Gettext now rejects it (it is because of
this message, BTW, that newer Gettext perform this check).

| * Change indentation in src/print.c.  I didn't see the need for this,
|   so I left this alone.

???

| * Change LIBOBJS to LIB@&address@hidden  I don't know why this change is
|   needed, so I left it out for now.  (Personally I think we should
|   drop the ansi2knr support, but now's probably not a good time to do
|   that on the maintenance branch anyway.)

Err, that's normally needed.  Weird that my Autoconf doesn't complain!

| * Modify configure.in to use Autoconf 2.52 rather than Autoconf 2.52g,
|   and modify a lot of other stuff that flows from this change (don't
|   use AC_CONFIG_TESTDIR, AC_FUNC_STRNLEN; move files config.guess,
|   config.hin).  I can see why Debian would want to avoid test versions
|   of Autoconf, but going back to 2.52 is too risky, so I installed the
|   following patch instead, on both the maintenance and development branches:

Excellent!  Thanks.

|       * configure.in (AC_PREREQ): 2.53.
