  * Fix search dirs used for pre-processing executables
  It was combining the executable's hs-source-dirs with the library's
  hs-source-dirs when pre-processing executables. This was inconsistent
  with the search path used for finding ordinary .hs files and with
  sdist and lead to confusing behaviour. See ticket #161.
  If an executable needs source files from the library then it must specify
  the right hs-source-dirs, including '.' if appropriate.
  The behaviour is that if hs-source-dirs is not specified then the default
  is '.' however if hs-source-dirs is specified then '.' is not implicitly
  added. If it's needed then it must be added explicitly. This was always
  the case for ordinary .hs files, this patch just brings things into line
  for files that need pre-processing.
