But we already do this in WinMain, which is called first:

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR
lpCmdLine, int iCmdShow)
{
    int result;
    void exceptionHandler(Throwable e) { throw e; }

    try
    {
        Runtime.initialize(&exceptionHandler);
        result = myWinMain(hInstance, hPrevInstance, lpCmdLine, iCmdShow);
        Runtime.terminate(&exceptionHandler);
    }
    catch (Throwable o)
    {
        MessageBox(null, o.toString().toUTF16z, "Error", MB_OK |
MB_ICONEXCLAMATION);
        result = 0;
    }

    return result;
}

This is the top-level exception handler where exceptions from within a
WNDPROC propagate to if they're not caught.
