Eh?  Your response below points to a "yes", AFAICS...

Ditto.

Umm, right.  That's why I said "might help" rather than point the OP
directly to it... :-)

Ah, yes, this is exactly the message I was thinking of (though I didn't
recall it being this complicated).  Thanks for including a pointer to it.
BTW, we're talking about linking C here, not C++.  The name mangling
differences will make C++ linking much more painful, IIUC.

FWIW, someone else has mentioned working on the DLL initialization code
quite recently -- he might benefit from this pointer as well.
