I got it to work with this program:

#include <stdlib.h>
#include <stdio.h>
#include <locale.h>
#include <libpq-fe.h>

int main(int argc, char **argv) {
        PGconn *conn;

        setlocale(LC_ALL, "");
        putenv("PGLOCALEDIR=C:\\Programme\\postgres\\share\\locale");

        conn = PQconnectdb("port=4711");
        if (CONNECTION_OK != PQstatus(conn)) {
                fprintf(stderr, "%s\n", PQerrorMessage(conn));
                PQfinish(conn);
                return 1;
        }

        PQfinish(conn);
        return 0;
}

Instead of setting PGLOCALEDIR in the code, you can also define
it as environment variable on your system, that is maybe better.

It must point to the directory where your message files are installed
(you have spanish message files installed, haven't you?).

The above program assumes that there is no database running
on port 4711, so you get an error message from libpq.
