Added full scope qualification to identifiers in binary_reverse class. This
was required, for some reason, when I compiled in CodeWarrior. Visual C++
did not require these qualifications, which seems to be the right interpretation
to me. The identifiers are defined as public in the base class and should be
be perfectly accessible in the derived class without qualification (the names
aren't overridden in the derived class). Nevertheless, with the full qualification,
the code compiles and runs in both environments.
