>Description:
In my code I made a copy&paste mistake and the result was as follows:

void ClassName::ClassName::method(){
  // do something
}

The crazy thing is that gcc compiled that file correctly (as there was only 
ONE ClassName). I recognized the syntax error because the Borland-compiler 
under windows exited with errors. You can add as many "ClassName::" as you 
want. gcc will always compile with no errors...

The compiled program is correct but I think gcc should exit with an error on 
that copy&paste mistake. What do you think? Can you reproduce the behavior?

I attached a file which showes up the effect. Just compile it wit 

gcc -c classname.cpp

and watch out for errors :)

Have a nice day
Andreas

class ClassName{
  public:
    ClassName();
    ~ClassName();
    void method();
};

ClassName::ClassName(){
}
ClassName::~ClassName(){
}
void ClassName::ClassName::ClassName::method(){
  // do something
}

g++ -c classname.cpp
