Should --with-gdal be made the default for 5.1? As I understand it both
r.in.gdal and v.in.ogr use GDAL; r.in.gdal will work without --with-gdal
as it uses the gdalbridge code (but anecdotal evidence suggests this may
be buggy) but v.in.ogr needs --with-gdal to be specified. So at least
the configure script should disable building v.in.ogr if --with-gdal is
not specified.

But I think it would probably be good to make GDAL an absolute dependency
for 5.1, as PROJ.4 is now. I intend to add some functions for exporting
the projection information in a location to other formats and this will
also use the ogrspatialreference functions in GDAL.
