If an interface is marked 'deprecated' then, presumably, at some point it
will be withdrawn and no longer available. The 'unavailable' attribute
makes it possible to mark up interfaces to indicate this status. It is used
quite extensively in some codebases where a single set of headers can be used
to permit code generation for multiple system versions.
From a configuration perspective, it also allows a compile test to determine
that an interface is missing - rather than requiring a link test.
The implementation follows the pattern of attribute deprecated, but produces
an error (where deprecation produces a warning).
This attribute has been implemented in clang for some years.
