This header needs to be included first, otherwise things can easily get really messed up. The current code only works by accident, because some other header already including it early enough - but a subtle change in include order can easy break it. Thus, always make sure the header is really included first. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
