[Gdal-dev] unable to load proj.4

[Ellen De Beuckeleer]

Hi Didrik,

I tried your suggestion and indead, I do not need the proj.dll anymore!

Unfortunatelly, I still have the difference in projection information as 
described below.

Some additional information on the problem: The expected value below is 
the one we used in our test on Linux, using Proj v. 4.4.8. Now after 
converting our project to Windows, using Proj v 4.4.9, our test fail. 
Could this minor version change make the difference?

Merci et bonne soiree,

Ellen
