Patrick,
We did some investigations on the projection list provided in your previous post!
First, some projection srids are not supported Proj4. We did find a search in Google and find nothing about them. So PLEASE make sure you want to use those projections, can you provides the projection strings for them instead of srids?
srid 3942
srid 3943
srid 3944
srid 3945
srid 3946
srid 3947
srid 3948
srid 3949
Second, we did find we should use different projection strings for x86 and x64 OS, the reason is the same as first talked about. Following is the string you probably take a reference.
