Subject: errors in DEFAULT_WIND in a location made from epsg code

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: grass-6.0.cvs_src_snapshot__2005_01_15

In the menu invoked by 'grass60 -gui' I set up a new location from an epsg code
'2174'. After entering it any g.region command gave:
 
ERROR: default region is invalid
line 13: <cols3: -1073745292>

Today I used this functionality as one of the examples for a bunch of ArcView
addicts of how easy it is to work in Grass6. We were rather impressed but not
with g.region's output ;).

The problematic DEFAULT_WIND looks as follows:

north:      1
south:      0
east:       1
west:       0
cols:       1
rows:       1

Ah, I see. g.proj is missing an update for the WIND3 integrated.
Fixed in CVS.

I regret but I can't now. It was a brief, one day seminar for foresters
looking for some alternatives to ArcView. And my part was to talk a little
about how to handle Polish projections in Grass and the usage of proj4 and
gdal for coordinates and GIS data reprojection. But maybe there will be 
another occasion if they decide to try Grass for real.
