No, C was never a "portable assembly language". Some people think so - they are wrong, and the result is that they are unable to write good C code because they completely misunderstand the language. C was designed to remove the need to write so much code in assembly. It was designed to /replace/ assembly for many purposes, not to be a new kind of assembly. One of the points of C is that it isolated most programmers from the need to deal with details such as the size of its basic types, thus making it easier to write code that works on a wide variety of systems. At the same time, it placed a strong emphasis on "implementation defined" behaviour - the C language does not define the sizes of its basic types, but any given C implementation /does/ define them. So you can write code that is portable across many systems, and you can also write code that is dependent on the details of a particular target. (C99 included types that make it easier to write portable code that needs to rely on some of these details.) It is a myth that C is a "portable assembly language" or anything of the sort. It is a misunderstanding to think that when using C, you do not have guarantees about the sizes of basic types or their representation.
