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 ;).
