AC_PREREQ specifies the minimum version being required by a
configure.in/configure.ac.

=> AC_PREREQ(2.13) does _not_ specify wanting autoconf-2.13 instead of
autoconf-2.5x.

[AFAIK, there exist some hacked versions of autoconf which try to apply
AC_PREREQ(2.13) to destinguish if a configure script wants
autoconf-2.13, but this behavior is beyond the definition of AC_PREREQ,
ie. is plain wrong.]

=> This patch is useless.
