guile/m4/localcharset.m4
Ludovic Courtès c2c2b5a49b Use Gnulib's `localcharset', with local patches.
This follows Bruno Haible's suggestion at
<http://lists.gnu.org/archive/html/guile-devel/2011-11/msg00055.html>.

* m4/gnulib-cache.m4: Add `gl_LOCAL_DIR'; use `localcharset'.

* Makefile.am (EXTRA_DIST): Add gnulib-local/lib/localcharset.[ch].diff.
  (TESTS_ENVIRONMENT): New variable.

* gnulib-local/lib/localcharset.c.diff,
  gnulib-local/lib/localcharset.h.diff: New files.

* test-suite/Makefile.am (TESTS_ENVIRONMENT): Add
  @LOCALCHARSET_TESTS_ENVIRONMENT@.
* test-suite/standalone/Makefile.am (TESTS_ENVIRONMENT): Likewise.
