enums

There has been a lot of grousing about the uselessness of the enum type
in C, most of it justified under the circumstances.  The circumstances
are that all versions of PCC that I know of are buggy in their treatment
of this type.

Enums were intended to be entirely equivalent to ints; just a way, really,
of defining names for constants understood by the compiler and subject
to the normal scope rules.

There was a clear choice here: enums as utterly separate collections of atoms,
more or less as in Pascal, or as ways of naming integers.  I chose the
latter after some waffling.  Unfortunately, some of the waffle batter
got mixed in with PCC and has stayed there.
