- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass is not allocated until runtime, you cannot initialize any static/global data structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so will just initialize with a NULL pointer. Instead, you can initialize using the address of the pointer returned by RUNTIME_CLASS and dereference that. By the time you have an opportunity to dereference it, it will no longer be NULL. - Sync CmakeLists.txt. - Random fixes for problems GCC spotted. SVN r1852 (scripting)
