Subject: Time zone changes due to Brazilian Summer Time

Dear sirs,

Below are the patches (with full comments) for adjusting zone
information for South America, due to Brazilian changing of beginning
and ending dates for adoption of summer time.  Patches can be applied to
version 7.36 (as available from ftp://elsie.nci.nih.gov at 2000/10/04
00:00 GMT), and they are in unified diff format.

I am also sending the full altered file, as a GNU-zip compressed
