The runtime is initialzed automatically in an executable because it has 
its own C 'main' entry point. That gets called first, the runtime does 
all its initialization, then it calls your D main function.

In a DLL, the entry point is DllMain, not 'main'. So the runtime is not 
initialized at startup and you have to do it manually. The same holds 
true if you create an application with a WinMain entry point instead of 
main.
