Pointer casts, unions and implicit conversions between arrays and pointers are some of the loop holes in C's type system. I have a somewhat portable implementation of the C type system in written in C, if people are interested. http://github.com/kstephens/ll/tree/master/src/ct It was orignally intended to generate dynamic and static FFIs for embedded languages. There is some support for C type introspection using debugging symbols or parsing C headers.
