See http://bugzilla.remotesensing.org/show_bug.cgi?id=18 + + <LI> Modified TIFFClientOpen() to emit an error on an attempt to + open a comperessed file for update (O_RDWR/r+) access.

Fix supplied by + Peter Skarpetis <peters@serendipity-software.com.au> + + <LI> Modified tiffio.h logic with regard to including windows.h. It + won't include it when building with __CYGWIN__. + + <LI> README: update to mention www.libtiff.org, don't list Sam's old + email address. + + <LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for + one tile/strip images with an offset, and byte count of zero.
