Fails to build with GDAL 2.0

[sebastic]

As reported in Debian Bug #802497, prepair fails to build with GDAL 2.0:

 error: invalid conversion from 'GDALDriver*' to 'OGRSFDriver*'

The full build log is attached to the bugreport, which GitHub didn't allow me to do here:
prepair_0.7-3_gdal-2.0.log

prepair needs to be patched to support GDAL 2.0,
please refer to the MIGRATION GUIDE FROM GDAL 1.11 to GDAL 2.0 for pointers.

Indeed we're still building against GDAL 1.1x only. The problem is that the changes that need to be made are backwards incompatible and we use homebrew to install gdal, and it is still at v1.11. When homebrew switchs to v2.0, we'll implement the change. In discussion: Homebrew/legacy-homebrew#42845

I realise it's not ideal for everyone, but moving the master to GDAL 2.0 wouldn't be either.

Supporting only GDAL 1.x or 2.x doesn't seem very sensible, is it not possible to support both with conditionals like this change for openscenegraph for example?

[hugoledoux]

That sounds sensible and rather simple, I'll do that asap.

Thanks for pointing it out.
