Is there an opensource MIDL?

[Kuba Ober]

Hi,

I'm putting up a cross-compilation environment for Qt/Win 
(Professional/Enterprise) so that it could be built (and the applications 
using it!) with crossmingw32 (http://www.ibib.waw.pl/~winnie).

In order to enable myself (and other people) to "natively" use ActiveX (and 
thus ActiveQT), I guess I need to find an IDL compiler, right? I think that 
Qt needs it for ActiveQT...

Do you folks, by any chance, know of an opensource midl compiler that I could 
use in my packages? Or is there something at least semi-functional in the 
works somewhere?

My web searches didn't turn up with anything...

Thanks,
Kuba Ober
