I suspect that all calls will be done using cdecl, passing 'this' as the
first parameter.  The thiscall thing seems to be MSVC specific.

At some point, I was attempting to make my own message loop.  They never got
deleted.  There's really a lot that needs to be done to make it cross
platform.  First, I think we're going to have to figure out how to import
stuff under linux.  In windows, I can do it by ordinal (and can get a list
of undecorated names using Dependency Walker), but I don't think you can do
this using linux.  And, of course, there's the issue of calling conventions.

I suspect that you'll crash and burn using thiscall. :)
