>Description:
When a derived class inherits from a base class
two member functions of the same name whose argument
signatures differ only in the const-ness of their
implicit object argument, g++ seems to be unable to
distinguish between those member functions.  It appears
to assume that all references to the name refer to the
member declared last.

This applies to member functions inherited from a private
base class and made public with a "using declaration".
It does not apply to methods inherited from a public base
class without a "using declaration".
>How-To-Repeat:
See description in attached file.  There is a brief,
self-contained program that elicits the error, and an
analysis of the resulting behavior.
>Fix:
Coding inline methods in the derived class that each
explicitly forward to the appropriate base class method
works around this bug, because overload resolution on
names declared in the invoking class's scope is not broken.

This is not an acceptable fix for a large existing code
base, since it requires knowing where all potential
occurrences are, and touching code for each of them.
