Maybe the best solution for that goes as follows:
1 - each platform implementer writes a C DEFUN that provides the most
    obvious and direct interface to the underlying API.
2 - we then compare the various resulting interfaces and come up with a Lisp
    library written on top of it which unifies them into
    a platform-independent interface.
3 - most likely along the way, the unification effort showed that some of
    the platform-specific implementations can be improved or need to be
    changed.

The idea here is that number 1 can be done by each implementer without
knowing anything else, whereas number 2 can be done by people like myself
who lack the platform-specific knowledge.
