59 'config' and 'm4' directories).
60
61 <li> SConstruct, libtiff/SConstruct: Added the first very preliminary

76 <li> tif_dir.c: When prefreeing tv->value in TIFFSetFieldV
77 also set it to NULL to avoid double free when re-setting custom
78 string fields as per:

81
82 <li> tif_dir.c: Fixed up support for swapping "double complex"
83 values (128 bits as 2 64 bits doubles). GDAL gcore tests now
84 pass on bigendian (macosx) system.
85
86 <li> libtiff/{tif_dirread.c, tif_dirinfo.c}: Do not upcast BYTEs to
87 SHORTs in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples()
88 function, use TIFFFetchNormalTag() instead as per bug
89 <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=831">
90 http://bugzilla.remotesensing.org/show_bug.cgi?id=831</a>
91
92 Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag()
93 instead.
94
95 <li> tif_print.c: Fixed printing of the BYTE and SBYTE arrays.
96
97 <li> tif_write.c: Do not check the PlanarConfiguration field in
98 the TIFFWriteCheck() function in case of single band images (as per
99 TIFF spec).
100
101 <li> libtiff/{tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_print.c}:
102 Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera,
103 ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom.
