The gettext info page says:

     But there is one little hook.  The code for gcc-2.7.0 and up
     provides some optimization.  This optimization normally prevents
     the calling of the `dcgettext' function as long as no new catalog
     is loaded.  But if `dcgettext' is not called the program also
     cannot find the `LANGUAGE' variable be changed (*note Optimized 
     gettext::).  A solution for this is very easy.  Include the
     following code in the language switching function.

            /* Change language.  */
            setenv ("LANGUAGE", "fr", 1);

            /* Make change known.  */
            {
              extern int  _nl_msg_cat_cntr;
              ++_nl_msg_cat_cntr;
            }
