Thanks for that Paul, the previous precompiled gdal had a bug when
importing files certain files that I needed.

I did come across the problem with libraries not being found:
libpng13.dll and zlib1.dll. I just renamed the files I had (libpng.dll
and libz.dll from the old wingrass-extralibs package) and it seems to
work. Not sure if they were the same version you used though and
whether it'll break something... it seems to be working so far
