I'm trying to build LibTiff for 64 bit Windows.
sure what's the best way to handle this problem in tif_win32.c I'm not

(in TIFFOpen()):

tif = TIFFFdOpen((int)fd, name, mode);

fd is a void * which is 64 bit on Windows, int is 32 bit.

This does seem like a problem, particularly if the extra bits are actually used. I don't believe that libtiff has been ported to 64-bit Windows even though it mostly works ok for 64-bit Unix systems. 64-bit Windows is strange since 'long' is still 32-bits.

Since this seems like a new area for libtiff, I recommend using the 4.0.0beta2 preliminary release, or libtiff CVS, so that it is easier to formulate and test fixes. Old releases are never fixed.
