In case anyone is actually reading this newsgroup, I figured out the
problem.

Seems the parser has a problem with the namespace block

namespace MyNameSpace{

int MyClass1::MyFunction(MyClass2* pC)
{
            return 0;
}

}

You have to do this:

int MyNameSpace::MyClass1::MyFunction(MyNameSpace::MyClass2* pC)
{
            return 0;
}

in fact it even has a problem if the namespace block is defined anywhere.

namespace MyNameSpace
{
   
   AnotherClass c;
}

int MyNameSpace::MyClass1::MyFunction(MyNameSpace::MyClass2* pC)
{
            return 0;
}
