I wrote a set of scripts and utilities a while ago that used
the LIBs and DLLs to generate export-level debug symbols
for the Symbian libraries (for WINS). They didn't work
with VS.NET, though. Recent postings to microsoft.public.vc.debugger
revealed why (the dll has to list the right .DBG file in
the debug directory) and Istvan Hajnal wrote a utility
that fixes the problem.

Putting all this together enables now debug symbols for
VS.NET as well :-) . Get the goods from
