[GRASSLIST:10697] Problems exporting raster using r.out.arc or r.out.gdal

[Tim De Chant]

I have a small raster data set (~400 rows and 350 columns stored in  
CELL format) that I'm trying to export to an external raster format.   
Ideally, I'd like to get the it into an Arc GRID format to compare it  
to the original data, but r.out.arc has been creating files that are  
absurdly large (5 GB and counting when I quit the process).  Should I  
not be using r.out.arc?  Could part of my problem be that the data is  
CELL formatted not FCELL or DCELL (the original data is in integer  
format)?

On a somewhat related note, I have also tried to export the data  
using GDAL from the GUI (using 6.1.cvs from Lorenzo's 060218 Mac OS X  
binary), but both d.m and gis.m freeze when I try to change the  
output format via the pulldown menu.  Is this a known bug?  I  
searched the bug list and couldn't find any info.  If it's new, I'll  
file it, but I wanted to check first.  Thanks.

Tim
