Not sure, really.

That seems a good place for it, yes. The compiler will
find that there.

Definitely. But then it's the module's author's turn to chime in.

Yep. Perhaps your hunch is correct, and you have a different version
of webkit2.h than the author has. Perhaps the author's even includes
<stdlib.h> and friends?
