    For '--disable-bootstrap' builds, we still have '-Woverloaded-virtual', and any
    new such diagnostics will be caught by the #1026 "check for new warnings"
    machinery, so effectively that does implement '-Werror', too.

    This reverts #1585 commit a32ef7aa18c45e7047f539b11cd572f0f9502b6d.
