[gdal-dev] autotest 1.6 errors - need help

[William Kyngesburye]

The configured GRASS prefix is already compiled into the OGR GRASS  
driver as GRASS_GISBASE, why not do the same for the GDAL GRASS  
driver?  (I thought it was, but GRASS_GISBASE only turns up in  
ogrgrassdatasource.cpp).

[Trillian]  What are you supposed to do WITH a maniacally depressed  
robot?

[Marvin]  You think you have problems?  What are you supposed to do if  
you ARE a maniacally depressed robot?  No, don't try and answer, I'm  
50,000 times more intelligent than you and even I don't know the  
answer...
