Hi. Consider the following case : template<typename T> struct Base{ void f() const {} int X; }; template<typename T> struct Derived : public Base<T> { void g() { X = X+X; f(); // LINE* } }; gcc does not require to write in "line*" : "this->f()", "this->X" But there are compilers that do require, they cannot resolve the symbol "f()" otherwise. I have a portable c++ code, besides this case. Is there some automatic way to find and correct all occurencies of such a case in the code? I always work with gcc, but I will need to port the code to vendor provided compiler soon (to sgi mipspro). Thank you. Dima.
