They're ugly and look like internal functions. I think just give them
nice names.

In fact, how about a wrapper function for the whole mess?

extern (Windows)
BOOL DllMain(HINSTANCE hInstance, ULONG ulReason, LPVOID pvReserved)
{
     return standardDllMain(hInstance, ulReason);
}

Any other required work can be done after the standard handler.
I make a lot of C-callable DLLs (in fact, it's ~75% of my D
programming) and they're all like this.
We might need a different wrapper for D-callable DLLs.

Obviously the low-level stuff needs to be available, but if there's a
simple wrapper, they can stay ugly.
