  11 //  See http://msdn.microsoft.com/msdnmag/issues/05/05/SafeCandC/default.aspx
  12 //  But the wording of the warning is misleading and unsettling, there are no
  13 //  portable alternative functions, and VC++ 8.0's own libraries use the
  14 //  functions in question. So turn off the warnings.
