Normally I just use dmc.exe, which takes care of everything, so I'm
mostly clueless. But luckily, it tells you what it's doing so I have a
rough idea of what's needed.

If you look at the link command, the last argument is a '.def' file,
this should contain instructions for the linker. This needs to be
generated in order to tell the linker to produce a DLL. Normally, dmc
generates one automatically which looks like this:

LIBRARY "library_name.dll"
DESCRIPTION 'library_name as a DLL'
EXETYPE NT
SUBSYSTEM WINDOWS
CODE SHARED EXECUTE
DATA WRITE

So if you can generate a file like that (with library_name changed to
whatever you require, and maybe a more relevant description), and pass
it as the last argument to the existing link command in dmc.jam, it
should produce a dll. The implib flag to the command tells it to
produce an import lib.

In case you need it, here's links to the relevant documentation,
although I think all you need to do (at least for now) is generate
that .def file.

I hope that helps. I look into this some more soon.
