Here's an example where such flexibility is useful: it allows the
"implementation-defined" equivalent-type of a enum to be "the narrowest
integral type that's capable of containing all values of the enumeration
constants".  Thus on such an implementation, enum {RED,BLUE,GREEN} would be
stored in a char-sized object, while still allowing for the existence of
large-range enums, which would be stored in a full word.
