commit 9e477d5451c1be9a5093537ea02a694a4575e119
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Define CTYPE for more Posix types
    
    See also b9f636b3aa962154c1b1515a3acecfbe9071b308 for explaination,
    as `unix` is slowly migrating to make more use of CApiFFI we need
    more accurately annotated CTYPES.
    
    (cherry picked from commit 6c7760b26133a0490f613895a37ff67045249fc8)
