why does strftime not respect my locale settings?

[Fritz Heinrichmeyer]

here is what locale says:
LANG=de_DE.ISO8859-15
LC_CTYPE="de_DE.ISO8859-15"
LC_COLLATE="de_DE.ISO8859-15"
LC_TIME="de_DE.ISO8859-15"
LC_NUMERIC="de_DE.ISO8859-15"
LC_MONETARY="de_DE.ISO8859-15"
LC_MESSAGES="de_DE.ISO8859-15"
LC_ALL=de_DE.ISO8859-15

but today

	strftime(buffer, 1000, "%d %A %B", localtime(&timev));

delivers

24 Friday February

        setlocale(LC_TIME, "de_DE.ISO8859-15");
        strftime(buffer, 1000, "%d %A %B", localtime(&timev));
delivers

24 Freitag Februar

how can i change strftime without setting locale explicitly?
