        * gutils.c (g_get_any_init): cleaned up the errno mess for
        GETPWUID. we especially don't want to g_error() out here!
        the warning for G_THREADS_ENABLED and !HAVE_GETPWUID_R isn't
        gcc related.
        if !HAVE_PWD_H and !NATIVE_WIN32, g_free the home dir before
        resetting it to NULL, why are we doing this anyways?
        reordered code a bit so we always provide defaults (except
        for g_home_dir).
