[darcs-devel] New extension systnax -WError? How do you want to solve this?

[Marc Weber]

Problem: (Lock.lhs)
  \begin{code}
  {-# OPTIONS_GHC -cpp -fffi #-}
  {-# LANGUAGE CPP, ForeignFunctionInterface #-}

results in:   Warning: -fffi is deprecated: use -XForeignFunctionInterface or pragma {-# LANGUAGE ForeignFunctionInterface#-} instead

found The Glorious Glasgow Haskell Compilation System, version 6.11
configure: error: Compile failed.

etc.. ?

Probably the best way is pasing -cpp all the time by default and then
using something like this:

  #if (__GLASGOW_HASKELL__ > 608)
  {-# OPTIONS_GHC -fbang-patterns -fffi #-}
  #else
  {-# LANGUAGE BangPatterns, ForeignFunctionInterface #-}
  #endif
