Below find proposed changes to files in the time zone package:
	* australasia, europe, and southamerica: changes by Halász Sándor Viktor to fix URLs.
	* africa: changes to reflect Mauritius's 2008-2009 DST experiment.
	* southamerica and zone.tab: changes to reflect Brazilian time zone realignments.

As usual, I plan to let these percolate over a weekend;
if no problems are found tzdata2008d.tar.gz should appear on 2008-07-07.

! # It seems that Mauritius observed daylight saving time from 1982-10-10 to

  # Decretos sobre o Horario de Verao no Brasil
  # </a>.
  
+ # From Paul Schulze (2008-06-24):
+ # ...by law number 11.662 of April 24, 2008 (published in the "Dirio Oficial da Unio"...)
+ # in Brazil there are changes in the timezones, effective today (00:00am
+ # at June 24, 2008) as follows:
+ #
+ # a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
+ # part of the Amazonas state that had this timezone now being put to the
+ # timezone UTC+4
+ # b) The whole Par state now is put at timezone UTC+3, instead of just
+ # part of it, as was before.
+ #
+ # This change follows a proposal of senator Tio Viana of Acre state, that
+ # proposed it due to concerns about open television channels displaying
+ # programs inappropriate to youths in the states that had the timezone
+ # UTC+5 too early in the night. In the occasion, some more corrections
+ # were proposed, trying to unify the timezones of any given state. This
+ # change modifies timezone rules defined in decree 2.784 of 18 June,
+ # 1913.
+ 
+ # From Rodrigo Severo (2008-06-24):
+ # Just correcting the URL:
+ # <a href="https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=3Ddo&secao=3D1&pagina=3D1&data=3D25/04/2008">

+ # </a>
+ #
+ # As a result of the above Decree I believe the America/Rio_Branco
+ # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
+ # be created to represent the the west side of the Para State. I
+ # suggest this new timezone be called Santarem as the most
+ # important/populated city in the affected area.
+ #
+ # This new timezone would be the same as the Rio_Branco timezone up to
+ # the 2008/06/24 change which would be to UTC-3 instead of UTC-4.
