FYI: s/gettextize/autopoint/

[Akim Demaille]

This patch is based on a prerelease Bruno had me tested.  First
experiences on Bison are very satisfying.  autopoint is a great tool,
and it is to be expected that its internal logic be copied by other
tools.

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
        autopoint instead of gettextize.
        ($uses_alocal): Rename as...
        ($uses_aclocal): this.
        * doc/autoconf.texi (autoreconf Invocation): Adjust.
        Suggested by Bruno Haible.

 ** Executables
 
-- autoreconf is adjusted to GNU Gettext 0.11.
+- autoreconf is adjusted to GNU Gettext 0.11.3.
+  Warning: It now relies on autopoint, available since 0.11.3.
+  This is much safer and much more satisfying than the previous
+  scheme based on gettextize.  Don't expect proper functioning
+  with older Gettexts.
+  Many thanks to Bruno Haible for autopoint!
