when using the code from "how-to-repeat" the following macro is emitted. The compilation works, but the warning is anoying.
warning: pasting "::" and "ostream" does not give a valid preprocessing token
>How-To-Repeat:
use the following statements:
#define MACRO(x) std:: ## x
or
#define MACRO(x) std::##x
the warning will be generated altough it works afterwards.
