GNU toolchain edition of GNU libintl 0.12.1

Most of the content of this directory is taken from gettext 0.12.1
and is owned by that project.  Patches should be directed to the
gettext developers first.  However, note the following:

* libintl.h comes from gettext, but is named libgnuintl.h.in in that
  project's source tree.

* The files COPYING.LIB-2.0 and COPYING.LIB-2.1 are redundant with the
  top-level COPYING.LIB and have therefore been removed.

* The files config.charset, ref-add.sin, and ref-del.sin are not used
  in this setup and have therefore been removed.

* aclocal.m4 was constructed following the instructions printed by
  "gettextize" from the files that gettext 0.12.1 installs in
  $(prefix)/share/aclocal.

* configure.in and Makefile.in were written for this directory
  layout, by Zack Weinberg <zack@codesourcery.com>.  Please direct
  patches for these files to gcc-patches@gcc.gnu.org.
