Description

See #514
We can find out the gcc version of the system by

IF(CMAKE_COMPILER_IS_GNUCC)
    EXECUTE_PROCESS(COMMAND ${CMAKE_C_COMPILER} -dumpversion
                    OUTPUT_VARIABLE GCC_VERSION)
    STRING(REGEX MATCHALL "[0-9]+" GCC_VERSION_COMPONENTS ${GCC_VERSION})
    LIST(GET GCC_VERSION_COMPONENTS 0 GCC_MAJOR)
    LIST(GET GCC_VERSION_COMPONENTS 1 GCC_MINOR)
   MESSAGE(STATUS "Found gcc version: ${GCC_MAJOR}.${GCC_MINOR}")
ENDIF(CMAKE_COMPILER_IS_GNUCC)

We could set USE_CPP_0X for affected GCC versions automatically ...

If c++0x activated, there are already compiler version checks to select individual features.
Globally activating/deactivating c++0x is not appropriate since this depends on an external bug (boost-thread).
