This looks really similar to the issue raised in ticket http://trac.osgeo.org/gdal/ticket/3292 that you reported almost 2 years ago ;-) but that did not see any progress unfortunately :-( Although not a specialist of the mapinfo format, I think the fix for EPSG:2154 should be straightforward (adding an entry in a table) once we know the mapinfo code that matches to the Reseau_Geodesique_Francais_1993 datum. One way to get it would be to attach the COMMUNEL93.TAB (and the other related files that make dataset) mentionned in http://georezo.net/forum/viewtopic.php?pid=197022 to the ticket. > > I try to sum up the issue in english in this email.
