Log Message:
make(1): add more type safety for enums

There are several types of flags for variables, and these cannot be
mixed.  To prevent accidental typos, these are defined in separate enum
types.  Clang warns about direct assignments between distinct types, but
not about mixing distinct types in binary expressions like A | B.  GCC
does not warn at all.
