locale functions on OpenBSD 3.5

I've installed binary packages (see below) from OpenBSD 3.5 CDROM. I'm having trouble with the locale functions (setlocale and localeconv). I have tried the following code with $sLocale set to '', 'en_US', 'de_DE', 'fr_FR', 'it_IT', 'C' and 'POSIX': <?php setlocale(LC_ALL, $sLocale='C); $aLocaleInfo = localeconv(); foreach($aLocaleInfo as $key=>$val) {

    echo "$sLocale.$key=$val<br>\n";

} ?> All produce the same output: C.decimal_point=. C.thousands_sep= (it_IT results in '.') C.int_curr_symbol= C.currency_symbol= C.mon_decimal_point= C.mon_thousands_sep= C.positive_sign= C.negative_sign= C.int_frac_digits=127 C.frac_digits=127 C.p_cs_precedes=127 C.p_sep_by_space=127 C.n_cs_precedes=127 C.n_sep_by_space=127 C.p_sign_posn=127 C.n_sign_posn=127 C.grouping=Array C.mon_grouping=Array After some research I found the setlocale 'C' function on OpenBSD has some bugs listed: http://resin.csoft.net/cgi-bin/man.cgi?section=3&topic=setlocale BUGS

     The current implementation supports only the "C" and "POSIX" locales for
     all but the LC_CTYPE locale.

     In spite of the gnarly currency support in localeconv(), the standards
     don't include any functions for generalized currency formatting.

     LC_COLLATE does not make sense for many languages.  Use of LC_MONETARY
     could lead to misleading results until we have a real time currency con-
     version function.  LC_NUMERIC and LC_TIME are personal choices and should
     not be wrapped up with the other categories.

So I have three questions: 1) Is there a connection between the C and PHP setlocale functions? 2) If PHP setlocale calls the C routine, then why don't PHP manuals indicate the function is platform/compiler dependant? 3) Are there any values of $sLocale that work on OpenBSD 3.5?
