[Dune] Dune on cygwin

[Ganesh Diwan]

Commenting out the Fortran part did help but cmake appears to have the
problem with config.h file in my build-cmake folder. I think the option of
CMAKE_LEGACY_CYGWIN_WIN32=1 is irrelevant as I used
64 bit Cygwin installation. Description of the error below-

CMake Warning at /usr/share/cmake-2.8.11.2/Modules/Platform/CYGWIN.cmake:15
(message):
  CMake no longer defines WIN32 on Cygwin!

  (1) If you are just trying to build this project, ignore this warning or
  quiet it by setting CMAKE_LEGACY_CYGWIN_WIN32=0 in your environment or in
  the CMake cache.  If later configuration or build errors occur then this
  project may have been written under the assumption that Cygwin is WIN32.
  In that case, set CMAKE_LEGACY_CYGWIN_WIN32=1 instead.

  (2) If you are developing this project, add the line

    set(CMAKE_LEGACY_CYGWIN_WIN32 0) # Remove when CMake >= 2.8.4 is
required

  at the top of your top-level CMakeLists.txt file or set the minimum
  required version of CMake to 2.8.4 or higher.  Then teach your project to
  build on Cygwin without WIN32.
