Hmm ... I tried this myself (I'm setup via Cygwin) and it worked. I remember when I used to use MinGW that I had to always get the latest bleeding-edge tools to make everything work. That's what annoyed me about MinGW and why I quit using it. I don't know if that helps any, but just wanted to note that it works for me on Cygwin (which is gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)).
