MAJOR CHANGES:

- LZW compression enabled by default. You don't need the separate compression kit anymore.
- bmp2tiff: Added new utility to convert Windows BMP files into TIFFs.
- The first attempt to implement a test suite.

CHANGES IN THE SOFTWARE CONFIGURATION:

- Many portability fixes in the new autotooled build suite.

CHANGES IN LIBTIFF:

- libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer overruns fixed, as noted by Chris Evans.
- BSD data types (u_char, u_short, u_int, u_long) is no longer used internally in the libtiff. Should result in simpler configuration and better portability.
- libtiff/tiff.h: Fix column tagging. Reference current Adobe XMP specification. Reference libtiff bug tracking system to submit private tag additions.
- libtiff/tif_dirread.c: Don't reject to read tags of the SamplesPerPixel size when the tag count is greater than number of samples as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=576.
- libtiff/{tiffio.h, tif_open.c}: Applied patches from Joris Van Damme to avoid requirement for tiffiop.h inclusion in some applications. Look for details here: http://www.asmail.be/msg0054799560.html.
- libtiff/{tiffiop.h, tif_dirinfo.c}: Fixed problem with the static variable as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=593.
- libtiff/tif_lzw.c: LZW compression code is merged back from the separate package. All libtiff tools are updated to not advertise an abcence of LZW support.
- libtiff/tif_dir.c: Call TIFFError() instead of producing warnings when setting custom tags by value. Reported by Eric Fieleke.

CHANGES IN THE TOOLS:

- tiff2ps: Avoid zero division in setupPageState() function; properly initialize array in PSDataBW().
