Did you consider backporting the C++ 11 checks from Qt5? Ah, reading the
rest you do. Wheezy is just a few months old, so might not be the best to
base on. What about other Linux distro's like Fedora or OpenSuse? What does
the current release contain and what does the last one have? Mac seems to
have clang3.1 available in 10.8 and possibly even 10.7 with a recent-enough
Xcode.

My personal opinion for a KDE4 based KDevelop is: forget about Windows. Its
simply too painful to setup a dev-env for a KDE4 app for anybody to be
interested in that as a 'spare time project'. Its just not a supported
platform for KDevelop at the moment.

If KDevelop starts to use KF5 you could re-consider this decision if the
frameworks KDevelop depends on dropped most/all of the huge dependency
stack they currently have and setting up a suitable dev-env has become much
easier (i.e. there are ready-made binaries that one can use to develop kde
apps).

Thats one of the major benefits that QtCreator has for me, its sooo much
easier to build and patch it on that platform.
