MAJOR CHANGES:

This is mostly bugfix release. Most important fix is the one related to wrong custom tag read/write code.

CHANGES IN THE SOFTWARE CONFIGURATION:

autogen.sh: aclocal and autoheader should be executed after libtoolize. Also add '-I .' to aclocal invocation to check current directory for macros.
nmake.opt: Link with the user32.lib in windowed mode. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=697
nmake.opt, makefile.vc: make it easier to rename the libtiff DLL.
configure, configure.ac: Added --enable-rpath option to embed linker paths into library binary.

CHANGES IN LIBTIFF:

tiff.h: Revert back libtiff data type definitions as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=687
tif_dirread.c: Do not forget about TIFF_VARIABLE2 when checking for tag count in TIFFReadDirectory() function. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=713
tif_getimage.c: Support for multiple-alpha-channelled RGB-images as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=718
tif_getimage.c: #define A1 bracketing for clean build on SunPro compiler.
tif_dirwrite.c: Always write TIFFTAG_SUBIFD using LONG type as per bugs http://bugzilla.remotesensing.org/show_bug.cgi?id=703 and http://bugzilla.remotesensing.org/show_bug.cgi?id=704.
tif_win32.c: Use char* strings instead of TCHAR in windowed mode as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=697
tif_dir.c, tif_dirread.c: Remove TIFFReassignTagToIgnore() call from the TIFFReadDirectory() function. TIFFReassignTagToIgnore must be removed in the future, as it was never used properly. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=692
tif_jpeg.c: Added a work-around in order to allow compilation with the heavily modified version of libjpeg delivered with Cygwin.
tif_dir.c: Properly handle tags, which have the uint32 counts. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=693
tif_unix.c: Make UNIX module compilable (and usable) on Windows.
tiff.h: Added Adobe DNG tags.
tif_aux.c: Set the appropriate ReferenceBlackWhite array for YCbCr image which lacks that tag (noted by Hans Petter Selasky).
tif_color.c: Division by zero fixed (Hans Petter Selasky).
tif_stream.cxx, tiffio.h: Added C++ stream interface contributed by Edward Lam (see http://bugzilla.remotesensing.org/show_bug.cgi?id=654 for details). Those who want to use C++ streams should #include .
tif_open.c: Removed close() in TIFFClientOpen() if file is bad. This is the callers responsibility. http://bugzilla.remotesensing.org/show_bug.cgi?id=651
tiffio.h, tif_win32.c, libtiff.def}: Added TIFFOpenW() function to work with the double byte strings (used to represent filenames in some locales). As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=625
tif_dirread.c: Fixed problem when fetching BitsPerSample and Compression tags of type LONG from broken TIFFS as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=662
tif_dirinfo.c: Fixed definition for TIFFTAG_RICHTIFFIPTC, the writecount should have uint32 type. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=662
tif_write.c: Fixed wrong if() statement in TIFFAppendToStrip() function as per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=660
tif_dirinfo.c: Change definition for TIFFTAG_EXTRASAMPLES field. The caller should supply a count when setting this field. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=648.
tif_jpeg.c, tif_ojpeg.c: TIFFTAG_JPEGTABLES should have uint32 count. Use this type everywhere.
tif_next.c: avoid use of u_long and u_char types.
tif_fax3.c: Fixed case with the wrong decode routines choosing when the incorrect Group4Options tag set. As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=323
tif_dirwrite.c: Fixed problem with passing count variable of wrong type when writing the TIFF_BYTE/TIFF_SBYTE tags in TIFFWriteNormalTag().
tif_compress.c: Zero division problem fixed (Vladimir Nadvornik, Dmitry V. Levin).

CHANGES IN THE TOOLS:

fax2ps.c: Be able to extract the first page (#0). As per bug http://bugzilla.remotesensing.org/show_bug.cgi?id=690
tiff2ps.c: Fixed wrong variable data type when read Position tags (Tristan Hill).
tiff2ps.c: Fixed wrong variable data type when read Resolution tags (Peter Fales).
tiffset.c: Check the malloc return value (Dmitry V. Levin).
