   Yes, 1999h reflects the right DST start and stop dates for Brazil,
   but decree 3188 of 1999-09-30 included the states of SE, AL, PE,
   PB, RN, CE, PI, MA and RR, further to those already mentioned in
   decree 3150 of 1999-08-23.  Please make the necessary changes in
   the Brazilian rules, since I am not familiar with the syntax.

It should be OK; those changes were installed soon after Decree 3,188
came out.

   As a consequence, I would like to suggest the following Brazilian time

I think the only difference between your suggestions and what's
currently in the tz database is the choice of the canonical
representative for each region.  The TZ database uses Sao Paulo where
you suggest Brasilia; Sao Paulo seems correct to me, since Sao Paulo
is larger.  For Tocantins, though, the TZ database uses Araguaina
instead of Palmas.  Here I'm not so sure which is right, since I don't
know which city is larger, and I don't know how distinctive a name
`Palmas' is.
