Subject: r.in.gdal import south utm projected gtiff as negative zone

Platform: GNU/Linux/x86
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: 6.1

r.in.gdal import south utm projected gtiff as negative zone. But in grass, region
utm zones south of equator not is negative in a newly created location (examples
below)

<<PROJ_INFO>>
name: UTM
proj: utm
ellps: SAD-69
a: 6378160.0000000000
es: 0.0066945419
f: 298.2500000000
zone: 22
south: defined

<<cellhd>>
proj:       1
zone:       -22
north:      6475848.30684486
south:      6256125
east:       426355.92252066
west:       254360
cols:       5733
rows:       7324
e-w resol:  30.00103306
n-s resol:  30.00045151
format:     1
compressed: 1

When 'g.region -d' is used, the raster imported with r.in.gdal not is visible.
The only way to work with it is using g.region 'raster=imported_gtiff'.
To fix the imported gtiff I edit the cellhd file changing -22 to 22, then all
is working fine.

This bug not is specific to grass 6 version, is the same for the version 5.

It should be (in the WIND file). And it is in the example you give below! 
How exactly did you set up the newly created location (which command etc?)

I created the location "IBA" with grass5 initialization module (interactive).
I use the same grassdb for 5 years. 

[sandro@localhost grassdb]$ cat IBA/PERMANENT/DEFAULT_WIND
proj:       1

rows:       11074

I create new locations from grass6 initialization module and the zone in the
WIND file is negative. So, the problem is in my old data files. Probably the
bug is in some grass5 version that I use in the past (including cvs).

Sorry for my mistake !!

Thanks a lot for your patience and help.

Sandro.

Yes, this was a long-standing bug in g.setproj (for many years) that was fixed
in October 2003.
