When reading and writing Mapinfo files, there is a problem detecting Lambert 93 / EPSG:2154.
There are incompatibilities between Mapinfo and Mitab. Mapinfo saves values for SP1 Standard Parallel) and SP2 projection parameters in a way, and OGR (MiTAB) reads it differently in the resulting TAB file.
Attached is a patch inverting the order of SP1 and SP2 when reading and writing TAB files, only for L93/EPSG:2154. It is applicable on the MiTAB version which is included with gdal révision svn 25454.
