Update gettext* to 0.19.3:

Version 0.19.3 - October 2014

* Bug fixes:
  - Fix xgettext mishandling of octal character escapes in C.
  - Fix autopoint infinite recursion with certain configure.ac.

* The po/Makevars file has a new field MSGINIT_OPTIONS, that can be
  used to adjust msginit's operation.  This is particularly useful for
  controlling line wrapping behavior together with MSGMERGE_OPTIONS
  and XGETTEXT_OPTIONS.

* Portability:
  - Building on Solaris 10 and 11 with Solaris Studio compiler is now
    fixed.
