Bug#802495: pprepair: Fails to build with GDAL 2.0

[Sebastiaan Couwenberg]

Control: tags -1 patch

I've patched pprepair to build successfully with GDAL 2.0 as
mentioned in the upstream bug report:

 https://github.com/tudelft3d/pprepair/pull/30

The patch is included in the package available in git:

 https://anonscm.debian.org/cgit/pkg-grass/pprepair.git/commit/?id=c0f3c35373cf85c4808d56db06b3491eb4f30700

I'm waiting for feedback from upstream before uploading a new pprepair
revision with this patch.
