REVISION SUMMARY
  Before this change, building on Python 2.7 on Windows fails due to
  S_IFLNK being undefined. This regression was introduced by
  a32a96079e2d <https://phab.mercurial-scm.org/rHGa32a96079e2d48005e7a1c23b208d729ff96768b> / D11518 <https://phab.mercurial-scm.org/D11518>.
  
  It worked on Python 3 because its pyport.h (which is included via
  Python.h) contains effectively the same code as added by this
  changeset.
