If you pass the following on the command line:

-L/SUBSYSTEM:windows:5

You can get rid of your WinMain function and use a standard main, 
while still getting a "windowed" app instead of a console app. 
Dropping the :5 would allow you to support Windows 9x, but DMD 
doesn't (or isn't going to) support that anymore anyway. I always 
add :5 for XP and higher.

When running with main, DRuntime stores the args, so you can 
access them anywhere in your program by importing core.runtime 
and accessing the Runtime.args property. I had assumed that held 
true when WinMain was used, but after scanning through the source 
I don't see that it is.
