Was tif_win32.c used in the build (without tif_unix.c)?  Using it may 
require editing a Makefile.  A potentially silly issue is if you 
forgot to pass the "8" TIFFOpen option to request BigTIFF format. 
Usually a large file issue is reported as a failure to seek.

I do seem to recall large-file issues with old MinGW.
