in file.c:
-------
        if (f = getenv("TMPDIR")) {
                (void)snprintf(name, MAXPATHLEN, "%s%s%sXXXXXX", f,
                                           *(f + strlen(f) - 1) == '/'? "": "/",
 pfx);
                if (f = mktemp(name))
                        return(f);
        }

        if (f = (char *)dir) {
--------
solution: swap getenv("TMPDIR") and (char*)dir :-))

The standard tempnam() function is supposed to use the TMPDIR env variable over all else if it is present.  The function is correct as written as far as I can tell.
