[Bug-gnulib] addext.c import from GNU patch 2.5.9

[Paul Eggert]

I merged this change from GNU patch 2.5.9 into gnulib.  Hmm, I now see
that coreutils made a similar change, but I like this version better
as it doesn't have a cast in it.

        * addext.c (addext): Use assignment rather than cast, to avoid
        warnings on some platforms.
