 This is mostly bugfix release. Most important fix is the one

	related to wrong custom tag read/write code.

<font size="+3">C</font>HANGES 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.

<font size="+3">C</font>HANGES 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.

	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

	for details). Those who want to use C++ streams should

	#include <tiffio.hxx>.</tiffio.hxx>

	
 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()

 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
