[El] BigTiff

[Hatzopoulos, Nikolaos]

I found out that gdal source has an internal libtiff that supports bigtiff
so if you compile it with  --with-libtiff=internal
enables BigTiff support :) so simple

Hi Nikolaos



I did a quick and dirty source package of tiff4, you'll find it at  http://www.r3-gis.com/upload/libtiff-3.99.6-1.el5.src.rpm. Could you try to build gdal and other tiff dependencies against this version?
