Hello,

KDECompilerSettings.cmake:176 adds -std=c++0x to CMAKE_CXX_FLAGS for GNU
compilers. Would it be possible to pass -std=gnu++0x instead?

Rationale:
  The underlying GCC is v4.4, which doesn't know -std=c++11
  yet, only c++0x.

  We can't use -std=c++0x here, because the QNX headers
  depend on some GNU extensions (nanosleep() was one that I
  saw), so it has to be gnu++0x, ie. STD C++ + GNU extensions.


I am not sure what's the best way to detect a QNX compiler, I am no CMake
expert.

Thanks,
Rafael
