New description:

 A whole lot of types are still missing from `System.Posix.Types` as noted
 in a TODO comment in the code:

 {{{
 --- ToDo: blksize_t, clockid_t, blkcnt_t, fsblkcnt_t, fsfilcnt_t, id_t,
 key_t
 --- suseconds_t, timer_t, useconds_t
 }}}

 Specifically the lack of a wrapper for `blkcnt_t` is causing trouble
 because it's forcing HFuse to re-implement `unix`'s `FileStatus` type to
 include the missing `st_blocks` field. See
 [https://hackage.haskell.org/package/HFuse/docs/System-
 Fuse.html#t:FileStat FileStat docs on Hackage].

 I have patches for `base` and `unix` ready to add wrappers for all the
 types the comment mentions, let's see if I can figure out how to use Phab
 ;)
