Update of /cvsroot/python/python/dist/src/Python
In directory usw-pr-cvs1:/tmp/cvs-serv7304

Modified Files:
Tag: release21-maint
bltinmodule.c ceval.c
Log Message:
Backport fixes for two nested scopes bugs.

frameobject.c: make sure free and cell vars make it into locals, which
makes eval work.

bltinmodule.c & ceval.c: make sure a code object with free variables
that is passed to exec or eval raises an exception.

Also duplicate the current trunk test suite in the 2.1 branch, except
for certain necessary changes: different warnings raised by 2.1, need
for __future__.
