Unfortunately, the web site domain has been lost a couple of times 
already.  These are the two official pages:

   http://www.simplesystems.org/libtiff/
   http://libtiff.maptools.org/

The simple answer as to what version of libtiff is required to support 
BigTIFF is that libtiff version v4 or later is required.

All that should be necessary to enable BigTIFF is to pass the 
additional flag "8" in the open flags string to TIFFOpen() or 
TIFFClientOpen().

Unfortunately, the page at 
http://www.simplesystems.org/libtiff/man/TIFFOpen.3tiff.html does not 
appear to be updated to include the above.
