Allocate to an "enum" type only as many bytes as it needs for
the declared range of possible values. Specifically, the "enum" type
will be
equivalent to the smallest integer type which has enough
room.
Warning: the -fshort-enums switch causes GCC to generate code
that is not binary compatible with code generated without that switch.
Use it to
conform to a non-default application binary interface.
