  Get asdl code gen working with Python 2.3.  Should continue to work with 3.0

  Fix this test so it runs again by importing warnings_test properly.
........
  r55167 | neal.norwitz | 2007-05-07 01:03:22 -0700 (Mon, 07 May 2007) | 8 lines

  So long xrange.  range() now supports values that are outside
  -sys.maxint to sys.maxint.  floats raise a TypeError.

  This has been sitting for a long time.  It probably has some problems and
  needs cleanup.  Objects/rangeobject.c now uses 4-space indents since
  it is almost completely new.
........
  r55171 | guido.van.rossum | 2007-05-07 10:21:26 -0700 (Mon, 07 May 2007) | 4 lines

  Fix two tests that were previously depending on significant spaces
  at the end of a line (and before that on Python 2.x print behavior
  that has no exact equivalent in 3.0).
