 From `compiler/main/DynFlags.hs` the warnings `-fwarn-alternative-layout-
 rule-transitional` and `-fwarn-pointless-pragmas` are default warnings,
 but (i) there is no documentation for the warnings and (ii) they are not
 listed as default warnings in the beginning of
 http://www.haskell.org/ghc/docs/7.6.3/html/users_guide/options-
 sanity.html.
