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.

* 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).

* 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.)

* 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:

        * configure.in (AC_PREREQ): 2.53.
