An enum has a type, yes, but a variable of that type is
not range-restricted.
enum { FOO=1, BAR=2 } x;
x = 42; // legal
Some see this as a flaw in C, and I'd have to agree that C's
enums are sort of half-baked. However, it allows things like
enum { COMMAND=1, DATA=2, STROBE=0x40, RESET=0x80 } flags;
flags = STROBE | DATA;

In this instance it's moot. The source under discussion tries
to mimic C11 thread support for systems that lack C11 but have
Pthreads. As a C11 imitation, it should not introduce gratuitous
identifiers not called for by the C11 Standard. (Some, of course,
are unavoidable: The Pthreads-related headers declare names that
the C11 Standard reserves for the programmer's use, and some of
those even have external linkage.)
