Although ANSI C allows the control expression to be of any
integer type, some older compilers do not permit it to be
of type *long* or *unsigned long*. ANSI C also permits
an implementation to limit the number of separate *case*
labels in a *switch* statement to 257 (that is, more than
enough to handle all values of type *char*).
(Just distinguishing "permits" from "ensures".)
