[Python-checkins] python/dist/src/Lib/test test_exceptions.py, 1.19, 1.20 test_warnings.py, 1.4, 1.5

[tim_one at users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv22424/Lib/test

Modified Files:
	test_exceptions.py test_warnings.py 
Log Message:
Stop producing or using OverflowWarning.  PEP 237 thought this would
happen in 2.3, but nobody noticed it still was getting generated (the
warning was disabled by default).  OverflowWarning and
PyExc_OverflowWarning should be removed for 2.5, and left notes all over
saying so.
