    c++: -Wdeprecated-copy and using operator= [PR92145]

    For the purpose of [depr.impldec] "if the class has a user-declared copy
    assignment operator", an operator= brought in from a base class with
'using'
    may be a copy-assignment operator, but it isn't a copy-assignment operator
    for the derived class.
