All components are available in both editions.

To tell you the truth, the only difference in the editions is the top-level 
files called LICENSE*.

That's just a matter of what we're able to provide as precompiled, given 
the limited server capacity to build and human capacity to test.

Binaries are just convenience. If the configuration you want isn't provided 
as a binary, you can always compile it yourself.

On the specific case of ActiveQt, it's available for everyone, but it only 
makes sense on Windows (obviously) and you require a compiler that knows 
how to compile it. As far as I know, only MSVC has that capability. 

As for Phonon, the situation is similar, but it's a matter of having the 
necessary interfaces in the windows.h and DirectShow headers. The stock 
MinGW distribution isn't new enough (or wasn't).
