grepping /usr/share/proj/epsg, I got this:
paulo at onix:~/gis_data/ibge/mapa_indice$ grep -A 1 Brazil /usr/share/proj/epsg
# SAD69 / Brazil Polyconic
<29100> +proj=poly +lat_0=0 +lon_0=-54 +x_0=5000000 +y_0=10000000
+ellps=GRS67 +units=m +no_defs  <>
# SAD69 / Brazil Polyconic
<29101> +proj=poly +lat_0=0 +lon_0=-54 +x_0=5000000 +y_0=10000000
+ellps=aust_SA +units=m +no_defs  <>

>From which I determined EPSG:29100 to be the case, however:

$ ogr2ogr -update -append -f "ESRI Shapefile" -s_srs EPSG:29100

only returns the usage pattern of ogr2ogr.

I know this isn't really a GRASS issue, but...
Paulo Marcondes = PU1/PU2PIX
-22.915 -42.229 = GG87vc (http://www.amsat.org/cgi-bin/gridconv)
