Manu:

Building DMD with MSVC results in a compiler that runs MUCH MUCH faster.
In the interest of making DMD releases as fast as possible, this should be
standardised.

How much faster?
And how much time does it take to compile DMD itself? I compile DMD almost every day, so I am interested in keeping this time quite low.

(On Windows I use G++ v.4.8, isn't it good enough to compile DMD, instead of MSVC?)
