<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>

<UL>
	<li> Applied patch from Patrick Welche (all scripts moved in the
	'config' and 'm4' directories).

	<li> SConstruct, libtiff/SConstruct: Added the first very preliminary
	support for SCons software building tool (http://www.scons.org/).
	This is experimental infrastructure and it will exist along with the
	autotools stuff.

	<li> port/lfind.c: Added lfind() replacement module.
</UL>

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>

<UL>
	<li> tif_dir.c: When prefreeing tv->value in TIFFSetFieldV
	also set it to NULL to avoid double free when re-setting custom
	string fields as per:
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=922">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=922</a>

	<li> tif_dir.c: Fixed up support for swapping "double complex"
	values (128 bits as 2 64 bits doubles).  GDAL gcore tests now
	pass on bigendian (macosx) system.

	<li> libtiff/{tif_dirread.c, tif_dirinfo.c}: Do not upcast BYTEs to
	SHORTs in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples()
	function, use TIFFFetchNormalTag() instead as per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=831">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=831</a>

	Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag()
	instead.

	<li> tif_print.c: Fixed printing of the BYTE and SBYTE arrays.

	<li> tif_write.c: Do not check the PlanarConfiguration field in
	the TIFFWriteCheck() function in case of single band images (as per
	TIFF spec).

	<li> libtiff/{tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_print.c}:
	Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera,
	ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom.
