This enables using the MS C runtime for Win32 programs, but you 
could already use VS for debugging thanks to cv2pdb (also written 
by Rainer!). Though, now that the debug information is not 
channeled through the CodeView format, it might be more accurate.

Win64 is COFF-only because OPTLINK is 32-bit-only, so PDB was 
DMD's only Win64 debugging format (not that that's a bad thing).
