Hi,

thanks, but it seems I missed minor things last time:

Try to be consistent with the spaces for each function call.

Maybe one of those is not really conistent wrt curly brackets

> +        V_UI8(pvargResult) = call_method(func, argspos, args, (DWORD*)&regs );
> +        break;
> +    default:
> +        V_UI4(pvargResult) = call_method( func, argspos, args, (DWORD*)&regs );
> +        break;

space issue again, maybe somewhere else too?


Otherwise I'm quite tempted to sign it off
