Yeah, I've use dlls made in gcc with dmd. You need to run implib
over the dll to get a .lib and then it works pretty easily.

implib /s mydll.lib mydll.dll


implib can be found in the basic utilities package at digital
mars.

Yes, this works in most cases, but when it does not, then you 
have to use DEF files and modify/add symbols. It is not 
complicated, just time-consuming...

Yes, it is possible.

Long ago i have dealt with this almost on a daily basis (we used 
Borland C++ Builder on Windows in the former company I worked 
for).

The easiest method is to use DEF files to create the import 
library. If you do not have it, you can use some tool that will 
analyse the DLL, make the DEF file for you, and then you modify 
it to your needs, and then create the import library for your 
target toolchain.

This article explains everything you need to know:
