    lib/libc/gen         fts.c 
  Log:
  In fts_build(), if we try to chdir and fail (e.g. due to lack of search
  permission), try to continue in FTS_DONTCHDIR mode.  Of course this
  won't work for long paths, but we can't descend more than one pathname
  component beyond the directory anyway if we lack search permission.
  
  Here is a transcript demonstrating the change, where oldls is ls(1)
  linked with the old fts(3):
  
          das at VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
          das at VARK:~> oldls t
          a       b       c
          das at VARK:~> oldls -l t
          das at VARK:~> \ls t
          a       b       c
          das at VARK:~> \ls -l t
          ls: a: Permission denied
          ls: b: Permission denied
          ls: c: Permission denied
  
  I had forgotten about this patch until bde reminded me.  He reports
  using it without problems for over a year.
