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 ;).
