To solve this, add '-ro' (read only) to the parameter/flags list:

VMAP0DIR=grass0/warmerdam/v0eur/vmaplv0/eurnasia

ogrinfo -ro -summary gltp:/vrf/${VMAP0DIR} 'polbnda at bnd(*)_area'
INFO: Open of `gltp:/vrf/grass0/warmerdam/v0eur/vmaplv0/eurnasia'
using driver `OGDI' successful.

Layer name: polbnda at bnd(*)_area
Geometry: Polygon
Feature Count: 5847
Extent: (-31.265751, 30.000000) - (179.999900, 81.857361)

Now feature count is 5847.

I assume that GDAL/OGR >= 1.2.5 works ok with a
recent OGDI version.
