Compiler Warning (level 1) C4806 (Windows CE 5.0)
'operation' : unsafe operation: no value of type 'type' promoted to type 'type'
can equal the given constant
This message warns against serious errors such as
b == 3, where
b has type bool. The promotion rules cause bool to be promoted to int. This is legal according to the ANSI C++ Working Paper, but it can never be true.
