That's a fair expectation, and in this case I must say that
the problem is essentially my fault.

Prior to the patch, tlibimp did not convert pointers to
built-in-interfaces to smart interface wrappers. It was always
intended that tlibimp do this, and (along with a number of 
other features that didn't quite make the cut), it was decided
to add the feature in the patch. I should have objected;
unfortunately, I did not know better at the time.

What happened is that the implementation file generator
attached to the type library editor also had knowledge of
the IProvider* type. So we patched that --- establishing
a disconnect: the generator, and the importer, would now
create code that was inconsistent with code generated
in the unpatched version. Unfortunately, there was no way
to teach the generator to automagically convert the unpatched
code; this has to be done by hand, by changing all
IProvider* references to IProviderPtr references and re-registering
the type library.

Note that there should be no problem whatsoever with completely
new projects: i've tested about a dozen now, and all of them
have worked flawlessly. The problem only exists in projects
taken from the unpatched version to the patched version.

When I get some free time --- say, in a week or so --- I will
do this (I haven't), and then post the results.
