The "de" may be an alias, but my understanding is that "de_DE" would be
the proper string to use.  Usually the "locale" program reports an error
if the combination is not valid.

Or you could have used (relying upon the environment variables)

        setlocale(LC_ALL, "");

But note that LC_ALL itself corresponds to an environment variable.
I usually do quick checks with a script that sets just the two that
are most important (note that it unsets LC_CTYPE, in case it is not
consistent):

#!/bin/sh
unset LANG
unset LC_ALL
unset LC_CTYPE
export LANG=$1
export LC_ALL=$1
shift
$*

> with-locale de_DE locale
LANG=de_DE
LC_CTYPE="de_DE"
LC_NUMERIC="de_DE"
LC_TIME="de_DE"
LC_COLLATE="de_DE"
LC_MONETARY="de_DE"
LC_MESSAGES="de_DE"
LC_PAPER="de_DE"
LC_NAME="de_DE"
LC_ADDRESS="de_DE"
LC_TELEPHONE="de_DE"
LC_MEASUREMENT="de_DE"
LC_IDENTIFICATION="de_DE"
LC_ALL=de_DE
