It's tacit at best I think.
Here is the most unclear part of POSIX.1-1990 in this area:
%%%
{_POSIX_JOB_CONTROL} If this symbol is defined, it indicates that the
implementation supports job control.
{_POSIX_SAVED_IDS} [similarly]
%%%
Note that it doesn't say that anything about a value.
The unclearness is moot for these particular constants in POSIX.1-2001,
since they are no longer optional and are required to have a value
greater than 0.
BTW, FreeBSD is perfectly non-POSIX.1-2001 conformant since it intentionally
doesn't support the _POSIX_SAVED_IDS mistake. I hope "appropriate
privilege" can be interpreted suitably weaselly to claim support without
changing the behaviour.
