setlocale (LC_ALL, "");

is rather more standard, and it will make sure LC_CTYPE etc. are
correctly set up (needed to know the output codeset).

LC_MESSAGES can be overridden by LANGUAGE and LC_ALL.  You might want
to try one of those instead of LC_MESSAGES.  Also, gettext caches
strings and only rereads messages if it's notified the environment has
changed.

The gettext manual recommends doing this:

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

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

Alternatively, you can bypass the caching and force gettext to check
the environment every time you use it by calling dcgettext() instead
of gettext().
