Randall,
Jim Kleckner, who posted the message I referred to, was apparently able to
load a gcc-built DLL in the same manner as an MSVC-built one. This seems
to indicate that the ABI is compatible, and the only problem was the
function name mangling. It was mostly a speculation on my part to relate
the subject issue to that one, but it'd be interesting to know if this
indeed was the problem.
