let's assume we have a well-populatyed symbol table in the lib
(which is usually the case, or, at least, not too hard a restriction).

that's not quite true.
actually, each platform (wintel, linux, ...) has a pretty well-defined
object file format (ELF under unix/linux, for instance).
current icc/linux and gcc/g++ work pretty well together in most cases, and
icc/windows and cl, too.

It is well understood that the envisioned python module would have to be
