and CVE-2013-2004; the addition of the _XEatDataWords API for use by
Xlib-based extension libraries, to help them avoid integer overflows when
it is necessary to discard data; removal of ancient, unused, incomplete
support for the Cray Unicos OS, and the DECnet and TLI transport types;
numerous improvements to compose files and locale data; man page macro
cleanups to improve compatibility with doclifter; and various other
