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;
}
