Also I posted a suggested solution to the dev list a while ago, but there 
were no comments.

For every mapset, or just for each location? If for every mapset, should 
it be inherited from whatever the setting for PERMANENT is, or just 
blindly set to dbf every time a new mapset is created? If it does have to 
be created for every mapset and inherited from PERMANENT, presumably the 
state of the DB connection for PERMANENT can't be determined without using 
Vectlib functions? But all the mapset/location-handling functions are in 
GISlib, and it would really not be a good idea to have GIS dependent on 
Vectlib functions (I think). So this is really quite complicated. Perhaps 
the functions that deal with the default database settings could be moved 
out of Vectlib and into GISlib.
