Well, turning off C++0x extensions, for C++98/C++03:</p> <blockquote> <p>In strict mode, with -tused, Compile succeeded (but remember, the Comeau online compiler does not link).<br> Compiled with C++0x extensions DISabled.</p> </blockquote> <p><strong>Oops!</strong></p> <p>Well, you biggie mine, as they say in Norway (literally translated to English).</p> <p>I'd try to report that to Comeau.</p> <p><strong>EDIT</strong>: since Prasoon has also answered, quoting the Holy Standard with his interpretation of that contradicting what I wrote above, well, OK, standadeese…</p> <p>§11.3/1 "The access of a member of a base class can be changed in the derived class…", and so on, which is as clear as can be (no interpretation required).
