 Replying to [comment:39 nh2]:
 > Is this related to https://ghc.haskell.org/trac/ghc/ticket/8144, and
 does its fix maybe improve the situation?

 Not very much, I believe, as the cases discuss here do not necessarily
 involve header files. But the fix for #8144 is of course a general
 improvement.
