The relevant section of the dpANS of 12/88 is 3.5.2.2.
To paraphrase: every enumeration constant must be representable
by an int; the enumeration type may be any type compatible with
int.  This means 'int', 'signed int', or 'unsigned int'.

It sounds like one of your compilers is noncompliant.

Enums were an early extension to C, so the first edition of K&R
doesn't define them.
