Neither of these types is allowed. Except for _Bool, all integer types have a corresponding type of opposite signedness. > The last stipulation is perverse but I don't see anything in "6.3.1.1 > Boolean, characters, and integers" which forbids it. In reading the C standard it's important to read widely. In this case the provisions you're missing may be found in section 6.2.5 paragraphs 4 through 9.
