Q_COMPILER_DEFAULT_MEMBERS and Q_COMPILER_DELETE_MEMBERS are now set starting from gcc 4.6. Pre-4.6 compilers implement a non-final snapshot of N2346, hence default and delete functions are supported only if they are public. Starting from 4.6, GCC handles final version - the access modifier is not relevant. Compiler error: qsharedpointer_impl.h:717:31: error: 'QEnableSharedFromThis<T>::QEnableSharedFromThis()' declared with non-public access cannot be defaulted in the class body Change-Id: If1d3d4696f91912a09ca72bd4aa1fb07f491a0cb Reviewed-by: Marc Mutz <marc.mutz@kdab.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
