  New Revision: 47611

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=47611

  Log:
    merge revision(s) 47591: [Backport #10242]
    
    * ext/pathname/lib/pathname.rb (SAME_PATHS):
      Pathname#relative_path_from uses String#casecmp to compare strings
      on case-insensitive filesystem platforms (e.g., Windows). This can
      return nil for strings with different encodings, and the code
      previously assumed that it always returned a Fixnum.  [Fix GH-713]
