If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.

Add PyEval_GetNestedScopes() which returns a non-zero value if the
code for the current interpreter frame has CO_NESTED defined.

- Add CONFIG_ARGS variable and use it to re-run configure rather than
  using config.status.  This prevents an infinite loop if configure

This fixes SF bug #410146 (python 2.1b shelve is broken).

This makes verbose-mode output easier to dig thru, and removes an accidental
