setlocale() fails under FreeBSD 4.8:

[Fri Oct 31 - 17:56:28 - root /httpd/php-4.3.3]# cat configure.log | grep locale
checking for locale.h... (cached) yes
checking for setlocale... (cached) yes
checking for localeconv... (cached) yes
[Fri Oct 31 - 17:56:45 - root /httpd/php-4.3.3]# 

In fact, setlocale returns FALSE but no E_WARNING or anything.

After looking in ext/standard/string.c it looks like it can happen when HAVE_SETLOCALE is not defined...

But HAVE_SETLOCALE is defined.

Another solution is that, setlocale() call fails:

retval = setlocale (cat, loc);

We've got an if (retval) { } but no else... 
According to freebsd's man, setlocale returns NULL on failure. 

I added:
else {
     /* setlocale failed */
     efree(args);
     php_error_docref(NULL TSRMLS_CC, E_WARNING, "setlocale failed!");
     RETURN_FALSE;
}

And I get the E_WARNING, so it means setlocale() call failed, but why ? the same scripts works fine under linux but not under freebsd4.8. 

After looking in /usr/share/locale, we have:

/usr/share/locale/fr_FR.ISO8859-1:
LC_COLLATE      LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

/usr/share/locale/fr_FR.ISO8859-15:
LC_COLLATE      LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

/usr/share/locale/fr_FR.ISO_8859-1:
LC_COLLATE      LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

/usr/share/locale/fr_FR.ISO_8859-15:
LC_COLLATE      LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

so it should work.

If I have change fr_FR to fr_FR.ISO_8859-1 in the setlocale call, the script works fine, isn't setlocale() supposed to use default charset which is ISO_8859-1 ? In any case the documentation does not mention that we have to add the charset under FreeBSD...

Reproduce code:
---------------
setlocale(LC_TIME, "fr_FR");
echo strftime("%B %Y",$timestamp);


Expected result:
----------------
TRUE
Octobre 2003

Actual result:
--------------
FALSE
October 2003
