- <LI>Use of "int8", "uint8", "int16", "uint16", "int32", "uint32", "int64", "uint64"
- typedefs is now deprecated. libtiff code and headers no longer use them,
- and use their C99 standard equivalents (with "_t" suffix). Those typedefs
- are still available, with deprecation warnings, but external code is strongly
- encouraged to use the corresponding C99 stdint.h types. The deprecated
- types might be removed in a future release.</LI>
- <LI>Removal of unused, or now useless due to C99 availability, functions in port/</LI>
