There was a discussion regarding this. This is not abour Platform 4.

The summary was:
- kdelibs need to be compilable with old compilers (all that Qt supports 
- linux-specific parts can require gcc 4.5 (kwin, kactivities ...) for 4.10, 
with possibility to be increased to 4.6 after 4.10
- other things left kinda uncovered, but I guess 4.5 if they don't care about 
mac osx with gcc 4.2.

KAMD-specific answer:

So, the library in kactivities is compilable with any C++ compiler that 
compiles Qt.

The service will not be built if the compiler doesn't support some C++11 
features. The build should not break, if it does, please report.

Required features for KAMD:
auto - gcc 4.4
lambda - 4.5
unique_ptr - 4.3
variadic-templates - 4.3

*Optional* features (macro-defined if not supported)
nullptr - 4.6
override - 4.7

So, no, Platform 4 doesn't require C++11.

I sometimes do this when the history of the branch is bad - in the case of 
refactoring most of the time.
