Yes.

I'll be posting full instructions on 
http://www.skydancer.demon.co.uk/gnu-win32/ soon, but basically you use 
the instructions for building a relocatable DLL. You need a
"--subsystem windows" on the ld lines and an appropriate "-e" parameter 
for your DLL entry point ("-e D_DllMain@12" in my case). Depending on how 
VC++ in configured, you'll need to do name mangling in your .def file - 
stuff like:

EXPORTS
	Command=Command@8

assuming you have a stdcall function called Command() with two parameters.
