If you use a main() function, DMD will add the runtime stuff for you.
But if you use WinMain as your main function, you have to initialize
manually.

For example, if you try to compile and run this app:

module win;

import core.runtime;
import std.c.windows.windows;

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR
lpCmdLine, int iCmdShow)
{
    int[] a;

    a.length = 5000;
    auto b = a[];

    return 1;
}

> dmd win.d -L/exet:nt/su:windows:4.0 && win.exe

You'll see that it crashes:
---------------------------
win.exe - Application Error
---------------------------
The instruction at "0x00407cf6" referenced memory at "0x00000000". The
memory could not be "read".
