I use the graphical interface of Grass6.0.0 Cygwin stable (feb

snap=-1 PROJ_INFO file not found for location N50kart
PROJ_UNITS file not found for location N50kart?!
what does 'g.proj -p' give?
XY location?
Projection of input dataset and current location appear to match.
?! NULL == NULL ?
can that ever be true for shapefiles? is .prj respected if it exists?
Yes... OGR reads the .prj file. If there is none there then OGR dataset
projection = 0 (XY) and if the same for location then the message about
projections matching will be (validly because XY == XY) reported.
I fixed v.in.ogr so it won't bother checking for proj_info and
proj_units
if the location is XY and will avoid the confusing warnings.

Vhen following Hamish, I get:
GRASS 6.1.cvs (N50kart):~ > g.proj -p
XY location (unprojected)
The shapefile was projected, is projected now, utm,wgs84,sone33n.
And the same thing happens when I make a projected location
(utm,wgs84,sone33n).
As you might understand, I am not used to grass. I am going to read some
manuals..
But the problem is not the projections, I believe.
When I try to present it on maps, only the boundaries of the areas show
up -
GRASS 6.0.0 (N50kart):~ > WARNING: coor files of vector 'p1a@PERMANENT'
is larger than it should be
(33479 bytes excess).
WARNING: Cannot display areas, topology not available
WARNING: Cannot display topology, not available
And the problem remains after projecting.
Thanks, Geir
