On second reading, I'm not sure I understand it either. (And I am
    a native speaker. :-)

Specifying -pedantic doesn't turn errors into warnings for
    g++. I don't think the phrase 'this option reverses that' is 
    intended to mean g++ swaps the meaning of -pendantic and
    -pendantic-errors; I think it is intended to mean -fpermissive
    downgrades many errors into warnings.
