Added back AC_PREREQ() to configure.in to work around the Debian/Ubuntu's autoconf wrapper which chooses the correct autoconf if AC_PREREQ is in the configure.in but chooses autoconf-2.13 for configure.in if AC_PREREQ is absent.  The check in maint/updatefiles can't tell if the autoconf is wrapper or not.
