Frank,

Sorry for the delay.

> Why did you expect 298.2572235629972 as the inverse flattening for WGS84?

I ran gdalinfo on my .tiff file command line and I got that number.
Below is part of the gdalinfo output:

*****

I think in the future we will have to do this ourselfs. I however, have
not much experience in adding stuff to a dll, so it might take some
time. If we do find a way to include the EPSG support files in the gdal
.dll I will post it.
