Ther is no implicit cast involved. You have a member function available for 
exactly the parameters given. So no cast here and there shouldn't be any 
problem with the QT_NO_CAST_ASCII flag at all.

The questions is rather: Is this member function available in all supported Qt 
versions? If so it should be no problem to change all code to use the compare 
operator.
