Or (indeed) call Win32 API (like CharUpperBuff) instead of CRT.

Seems to me that if we use the ChTraitOS string traits for CStringT (instead
of the default traits for MFC strings), CharUpperBuff is called instead of
the broken CRT routine:

<code>

void CTestUpperCaseDlg::OnBnClickedMakeUpper()
{
    // Get string from user input
    CString input;
    m_txtInput.GetWindowText(input);

    // Use the ChTraitOS traits for CString, in this way CharUpper is called
    typedef CStringT< TCHAR, ChTraitsOS<TCHAR> > CStringOS;

    // Convert to upper case *properly*
    CStringOS inputAtl = input;
    CStringOS upper = inputAtl.MakeUpper();

    m_txtUpper.SetWindowText(upper.GetString());
}

</code>
