Sure, but it doesn't solve James' problem. If James could create the
import libraries with all the data marked DATA, it would imply he
already *knows* which these data items are! Once you know, one tricky
part of porting a legacy application over -- after this, it's a matter 
of searching for the symbol names and attaching dllimport attribute
in user code.

However, your point is well taken that we should go and fix dlltool.
I believe I did fix it locally at one point, but definitely didn't
submit the changes (don't remember why, perhaps it didn't work).
Contributions welcome of course.
