* New upstream version.
* Bumped Standards-Version to 3.7.2. No changes needed.
* Use {binary:Version} field in libgpg-error-dev dependecy field. (Closes: #384376)
* Fix typo in upstream URL at debian/copyright file (Closes: #387735)
* debian/patches: Disable m4_macros and 10_relibtoolize patches.
Upstream uses now a quite current copy of gettext.
* Update FSF address in debian/copyright file.
