Yeah, though if you add 1 more layer, i.e.

extern(C) main(..)

int WinMain(..)
{
     return main(1, &cmdline);
}

void main()
{
     try
     {
         real_main();
     }
     catch(Exception e)
     {
         MessageBox("oh man" ~ e.toString());
     }
}

void real_main()
{
   ..crap..
}

it's not so bad.
