Hmm.  That's a good question.  objdump will also display this
information, in a much different format, but it doesn't look like it
offers this kind of info either.

Maybe you need to do a two pass operation, looking for all of the
exported symbols first, and then using that information to either
prodice a def file or add declspec(dllimport) to the appropriate
declarations.
