To all, I stand abashed - don't try this without a trained instructor. I
misread the Schildt quote and (I think) wasted your time(s).
Thank you

gcc doesn't implement Schildt's book, it aims to implement

access specifier of 'private' has no effect.

operator=() is private in ios_base. Using private inheritance of
ios_base the program below fails in the constructor when '=' is used
(but not during memory initialization). I don't understand why
assignment is prohibited.

Perhaps I misunderstand your question, but
operator=() is private in ios_base. Using private inheritance of ios_base the
program below fails in the constructor when '=' is used (but not during memory
initialization). I don't understand why assignment is prohibited.
