What "Windows conventions" it doesn't follow?
Any way, for what I see, MingW (or perhaps, more corretly, MSYS) 
"sanitizes" each program (at least non-Unix ones) that is run by the 
bash shell by adapting the program arguments and environment variables 
from Unix paths to Windows paths. In this process the TEMP env var is 
translated incorrectly from "/tmp" to "c:/home/phoenix/LOCALS~1/Temp" 
(the slashes remain Unix ones)

Not something I am in any way willing to do. Unless it's changing to 
Cygwin (if it is any different).
Hum, now that I see it, Mingw seems to be a bit stale, the last version 
of MSYS is from 2004. Maybe I should haste my change to Cygwin? (I was 
already thinking of changing, but for other reasons)

And by the way, how about folding rdmd's functionality into dmd itself? 
It shouldn't take too long. :)
