I managed to answer all of the questions correctly; I recognized them as undefined. Still, there may be enough definition on the set of computers the program will run on, to do, in some cases (for example, that char is at least 8-bits, and/or that it is ASCII).
But the thing that would be better to do, in my opinion, may be like having LLVM with macros (including standard macros for dealing with differences of systems, and user-defined macros for your own use).
