The language is defined by the standard, not >by the behavior of the compiler you are using. There are definitions of the language and there are implementations of the language. The two frequently fail to coincide. If I rely on a property of the language that is defined by standard but poorly im- plemented, I will end up writing poor programs that exhibit many problems. If I rely on a property of implementations that is widely supported even though deprecated by the standard, I will end up writing better programs. I am paid to produce programs that work, not programs that use a language in conformance to a standard. If it were my business to develop compilers that conform to standard, I would probably feel differently. -- Chris Green Advanced Technology Center Laguna Hills, California
