Correct. The QXmlStreamXXXX classes are now a mess. They are technically a 
source- and binary-compatibility break on Mac (32-bit). But it works just 
fine if you #include <qxmlstream.h> and you don't offer API in a library 
containing those classes.

Anyways, here's what I suggest: a simple bundle of .cpp and .h files. 
Anyone who wants to use this copies into their projects (svn:externals or, 
if we were using Git, git-submodule).

Using kdesupport (external project) won't work here because of the kdelibs 

The other option I see is a new "/trunk/kdetemporary" module that inserts 
itself in the dependency chain between kdelibs and kdebase (same level as 
kdepimlibs). This module would be managed as kdesupport: i.e., no 
"kdetemporary" release, but a release of each inner component. Which means 
someone must produce tarballs, so that in a few years' time, if someone 
wants to build KDE 4.3, they know where to find the dependency.

But with this module, it's possible to create shared libraries: as long as 
the soname changes for every BC-breaking release.

I don't like this precedent.
