//  VC++ 8.0 warns on usage of certain Standard Library and API functions that

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