-+* First cygwin64 build
-+
-+----- autoconf2.1-2.13-11 --  unreleased -----
-+* 64bit only release; release-number skipped
-+
-+----- autoconf2.1-2.13-10 -- 18 Oct 2008 -----
-+* routine rebuild; use stock cygport
-+* This version marks the beginning of cygwin-1.7 specific
-+  ports. Releases -4 thru -9 are reserved for cygwin-1.5.
-+
-+----- autoconf2.1-2.13-3 -- 15 Nov 2006 -----

-+2.13-1
-+---------
-+first release in unified distribution -- older releases on cygwin
-+installed autoconf-2.13 into /usr/autotool/stable and relied on 
-+kludgy wraper scripts.  This release is the first to install both
-+versions of autoconf into /usr, and use Red Hat-derived non-kludgy
-+wrapper scripts.
