Hmm, the source says:

            # The MSVC linker generates .lib and .exp files, which cannot be
            # suppressed by any linker switches. The .lib files may even be
            # needed! Make sure they are generated in the temporary build
            # directory. Since they have different names for debug and release
            # builds, they can go into the same directory.

Don't the debug builds have the "_d" suffix ? This should avoid
any problems with mixing the two.

About 3): if your import lib uses the same name as a common
DLL then your lib should probably use a different name, since
this would cause problems sooner or later anyway.

Unless, of course, I've overlooked something here -- I'm not
much of a Windows guy ;)
