----------------------------------------------

 * GNU gettext is included for systems that do not provide it.


Noteworthy changes in version 1.2 (2006-03-03)

   so it does not need to be called explicitely.  The header file
   defines GPG_ERR_INITIALIZED in this case.  This is experimental for
   now.

   evaluate to plain numbers, but expressions.  If you want to
   cross-compile, you might have to set CC_FOR_BUILD, though.

   strings is provided.

 * Interface changes relative to the 0.6 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
GPG_ERR_LOCALE_PROBLEM          NEW
