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

Verify checkins to p3yk (sic) branch go to 3000 list.

Fix this test so it runs again by importing warnings_test properly.

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).
