[gdal-dev] GDAL and NUTM17 NAD83 datasets.

[Daniele Romagnoli]

Hi again Frank.
My fault :(

I performed some tests on java bindings for Gdal 1.5.0 and I moved GDAL_DATA
from gdal-1.4.4/data to gdal-1.5.0/data.
I badly thought that the GDAL_DATA content was the same in the 2 versions
while the 1.4.4 looks for a ecw_cs.dat while the 1.5.0 looks for a
ecw_cs.wkt.

My fault... sorry.
Regards,
Daniele
