What does gdalinfo report about your file? My first guess would be that it
is being converted on the fly to RGBA mode by GDAL and this is defeating your
classification.

Hi=20
I have created the VC++ 6.0 workspace and project for MapServer. I =
haven't got a chance to create projects for all its libraries. If you =
need the one for mapserver, let me know, I can send it you.
