Windows MinGW and DMD

[David]

So I want to make the compilation of my little game work on Windows, I 
set up MinGW with Msys and ran the makefile, after a few fixes 
compilation worked, the problem is linking fails hard.

I need a few external libraries in C like glfw3 and openssl, latter I 
installed with `mingw-get install msys-libopenssl` and I compiled glfw3 
with the makfile and gcc.

Now how can I link this all together? I have .a static libs (which are 
.lib libs, after renaming?) and .o files from gcc (I have a few C files) 
and .obj files from dmd.
I hope you can help me out, because I have no idea how that kind of 
stuff works on Windows and I heared it's a real mess with OMF and COFF.

Thanks.
