Problem using Gdal-1.2.6

[Johan Hallgren]

I have installed MapServer 4.6.0-beta1 and now I will add tiff as
supported input format. I downloaded Gdal-1.2.6 and compiled it (the dll
and lib was created).

I uncommented the GDAL options in nmake.opt
GDAL=-DUSE_GDAL
GDAL_DIR=C:/SE/GMS/ms/gdal-1.2.6

Then I buildt the mapserver with:
nmake /f makefile.vc

Then I what supported format I had and found out the following:
C:\SE\GMS\ms>mapserv -v
MapServer version 4.6.0-beta1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP OUTPUT=SVG SUPPORTS=FREETYPE INPUT=SHAPEFILE DEBUG=MSDEBUG

Checking the formats in Gdal gives:
C:\SE\GMS\ms\gdal-1.2.6\apps>gdalinfo --formats

Any ideas?
