[Wine]source level debugging with WineLib?

We just started using WineLib, and have very basic question:

  which -g??? option do you use to do source level debugging
  with winedbg?

I searched the documentation and mailing list for any step-by-step
about this, but found nothing.  So either the answer is so obvious
that I just can't see it - or it doesn't work?

By default, winemaker seems configure things for no debug - so I
edited one Makefile manually, and added -g.  Winedbg can attach
to the process, and can even show the stack - but didn't know
much beyond that.  I tried all the -g variants that I could find,
but only -gstabs and -gstabs+ seemed to help.  They allowed the
debugger to find the correct place in the source, and "whatis"
seemed to work - however, if I tried to dereference something,
it complained about "no type ...", like this:

Any help?
