Update of /cvsroot/python/python/dist/src/Python
In directory usw-pr-cvs1:/tmp/cvs-serv20939

Modified Files:
	compile.c 
Log Message:
Add warnings for arguments named None.  All set.  (I could add a
warning for 'global None', but that's either accompanied by an
assignment to None, which will trigger a warning, or not, in which
case it's harmless. :-)
