  doctest assumed that a package's __loader__.get_data() method used universal
  newlines; it doesn't.  To rectify this the string returned replaces all
  instances of os.linesep with '\n' to fake universal newline support.

  Backport candidate.

  Final fix for #1403
  The Windows installer and some Linux distros are using compileall to compile all py files in the Lib/ directory. However no test exists to check if all py files can be compiled. I figured out that make testall is the easiest way to test compileall.
