In short - no. If you think about it, it would be insane - to test whether platform has some api/function, to use it in the code and deal in runtime with the case that platform actually doesn't implement this api/function. It just can't work. In reality autoconf (or something similar) is used to test whether symbol exist in library (or define in header etc) and in the code it's assumed that a feature behaves like described in standards (or as it does in Linux, but that's another issue ;). -- Hasso Tepper
