if you are referring to this: http://gcc.gnu.org/gcc-3.4/changes.html from the section starting: "The cast-as-lvalue extension has been removed for C++ and deprecated for C and Objective-C. In particular, code like this: " then that is just that GCC has caught up with MS compilers in dissallowing the implicit lvalue return of standard C style casts Still appears to be perfectly legal to cast to an explicit lvalue type... Please correct me if i am wrong on this... At least in my head it certainly seems to make no sense to take out casting to a modifiable type... Regarding Ola Olsson: static_cast is a little bit safer, as the types Cavey Gerard was referring to were reasonably compatible. AFAIK reinterpret_cast is used to allow you to do more "dodgy" casting, e.g. between a function pointer and a float, something which static_cast does not do... Again, please correct me if i am wrong.
