--- Comment #1 from Eric Fiselier <eric at efcs dot ca> --- Ping. I keep hitting this more and more. GCC seems to be warning because the declaration includes the CXX scope specifier "::foo". Removing the "::" seems to work. However, removing the "::" causes the code to take on a different semantic meaning. The warning shouldn't be issued in either case.
