I like to use implib like this:
 implib odbc32.lib odbc32.def
(where I provide a .def file)

The trick, of course, would be to find a .def file.

There are some available in the binding project at dsource, such as:
http://www.dsource.org/projects/bindings/browser/trunk/def/odbc32.def

But that might not have all of the definitions. You could also try using linkdef:
http://www.dprogramming.com/linkdef.php

Finally, I've attached a .def file that has many more definitions than the one in
the bindings project. I expect it'll will work for you, but I can't test it for
you (obviously).

I think that Walter has made a tool available that helps with turning a .dll into
a DMD-compatible .lib, but I don't recall the details.

(This is a common topic, so I guess someone should write a wiki page about it.
Maybe I'll do that eventually.)
