SDL_gfx binary available anywhere?

I’d like to use some of the functions available from SDL_gfx, but I can’t find the DLL anywhere. I’ve got the source code, which would be really great if I was an experienced C programmer, but I’m not. I use Delphi and access SDL through the JEDI-SDL headers. I tried downloading mingw, but I just can’t get the thing to compile. Where can I download the DLL?
