Description

Ogrinfo should return the following projection information for a TAB file with epsg:25832 projection:

PROJCS["unnamed",
GEOGCS["unnamed",
DATUM["European_Terrestrial_Reference_System_1989",
SPHEROID["GRS 80",6378137,298.257222101],
TOWGS84[0,0,0,-0,-0,-0,0]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]],
PROJECTION["Transverse_Mercator"],
PARAMETER["latitude_of_origin",0],
PARAMETER["central_meridian",9],
PARAMETER["scale_factor",0.9996],
PARAMETER["false_easting",500000],
PARAMETER["false_northing",0],
UNIT["Meter",1.0]]

But GDAL versions after 1.4.0.0, ogrinfo returns:

PROJCS["unnamed",
GEOGCS["unnamed",
DATUM["WGS_1984",
SPHEROID["WGS 84",6378137,298.257223563],
TOWGS84[0,0,0,0,0,0,0]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]],
PROJECTION["Transverse_Mercator"],
PARAMETER["latitude_of_origin",0],
PARAMETER["central_meridian",9],
PARAMETER["scale_factor",0.9996],
PARAMETER["false_easting",500000],
PARAMETER["false_northing",0],
UNIT["Meter",1.0]]

Just verified same error exists using GDAL 2.2.0dev from gisinternals.

I have found the problem in gdal-1.10.0/ogr/ogrsf_frmts/mitab/mitab_spatialref.cpp and here is the patch that works for our GDAL build.
