Use macro to define the number of enum values

Browse Source 
Refactoring in the interest of code consistency, a follow-up to 2e068db56e.

The argument against inserting a special enum value at the end of the enum
definition is that a switch statement might generate a compiler warning unless
it has a default clause.
