Comment (by riastradh):

 Elaborating on the unused attribute: the warning -Wunused-local-typedefs
 fires specifically for typedefs within a function body.  If you're not
 comfortable relying on typedefs within a function body to work (which may
 be an extension to C99, don't remember offhand), then you can proscribe
 the use of CTASSERT inside function bodies and omit ATTR_UNUSED.  If you
 are comfortable relying on typedefs within a function body to work, then
 you may want to keep the ATTR_UNUSED.
