proposed time zone package changes--Paraguay, core dump avoidance

Wed Feb 24 13:55:28 UTC 2010

Below find proposed changes to the time zone package:

	localtime.c	more core dump avoidance work
	southamerica	changes to Paraguay DST rules from 2010 forward

If no problems are found, these are to show up on the ftp site on 2010-03-01.

(I'm trying to get a good reference before making Bangladesh changes;
I'm trying to get starting- and ending-time-of-day information--and trying
to learn whether or not DST was actually observed in 2009--before making
Samoa changes.)
