Log Message:
Update to version 8.4.18.  Distilled list of non-Windows changes:

        * generic/tclInterp.c (Tcl_GetAlias): fix for [Bug 1882373]

        * generic/regguts.h, generic/regc_color.c, generic/regc_nfa.c:
        Fixes for problems created when processing regular expressions that
        generate very large automata. An enormous number of thanks to Will
        Drewry <wad%google.com@localhost>, Tavis Ormandy 
<taviso%google.com@localhost>, and Tom
        Lane <tgl%sss.pgh.pa.us@localhost> from the Postgresql crowd for their 
help in
        tracking these problems down. [Bug 1810264]

        * unix/tclUnixCompat.c (TclpGetHostByName): Really applied
        the change noted on 2007-11-13 by dkf below.

        * generic/tclIOUtil.c (TclGetOpenMode): Only set the O_APPEND flag
        * tests/ioUtil.test (ioUtil-4.1):       on a channel for the 'a'
        mode and not for 'a+'. [Bug 1773127] (backport from HEAD)

        * generic/tclCmdIL.c (Tcl_LsearchObjCmd): Prevent shimmering crash
        when -exact and -integer/-real are mixed. [Bug 1844789]

        * generic/tclThread.c: Back-port locking changes from Tcl8.5
        in Tcl_Mutex/ConditionFinlize. Now we properly master-lock
        the finalization of sync primitives.

        * generic/regc_nfa.c:   Fixed infinite loop in the regexp compiler
        * generic/regcomp.c:    [Bug 1810038].  Corrected looping logic in
        * tests/regexp.test:    fixempties() to avoid wasting time walking a
        list of dead states [Bug 1832612].  Convert optst() from expensive
        no-op to a cheap no-op.  Improve newline usage in debug output.

        * unix/tclUnixCompat.c (TclpGetHostByName): The six-argument form of
        getaddressbyname_r() uses the fifth argument to indicate whether the
        lookup succeeded or not on at least one platform. [Bug 1618235]

        * generic/regc_lex.c (lexescape): Ensure that backreference numbers
        can't overflow a signed int in a way that breaks things. [Bug 1810264]

        * generic/tclParse.c (Tcl_ParseBraces): fix for possible read
        after the end of buffer, [Bug 1813528] (Joe Mistachkin).

        * generic/tclObj.c (Tcl_FindCommandFromObj): fix finding a deleted
        command; cannot trigger this from Tcl itself, but crash reported
        on xotcl. This check is new to 8.4 but exists in 8.5, so this is a
        backport or something. Thanks Gustaf Neumann.

        * generic/tcl.h (Tcl_DecrRefCount): Update change from 2006-05-29
        to make macro more warning-robust in unbraced if code.
