And now try the same on windows :) It is also possible to use 2k5/8
binaries with VC6 binaries but that's a call for troubles.

It is often possible to do many things (even different architecture
support) on unix/linux and sometimes with windows. But we don't
support that, that's what I meant with "you can't". I should have
said: "You can but it is not supported" :)

Cheers,
