[PATCH] Removal of autoconf 2.13 support.

Stephen> configure.in is going away very soon. The following is the way that I think it should be done. Since autoconf-2.59 support seems stable, configure.in will be replaced with the 3 lines listed below and etc/configure-2.13 will be removed. ChangLog: 2005-09-17 Malcolm Purvis <malcolmp(a)xemacs.org&gt; * configure.in: Replace with warning to use autoconf 2.59. etc/ChangeLog: 2005-09-17 Malcolm Purvis <malcolmp(a)xemacs.org&gt; * configure-2.13: Remove. autoconf 2.59 support is stable. configure.in: --------------------------------------------------------------------------- # XEmacs now used autoconf 2.59. Please use configure.ac. AC_PREREQ(2.59) --------------------------------------------------------------------------- -- Malcolm Purvis <malcolmp(a)xemacs.org&gt;
