  58         <li> Applied patch from Patrick Welche (all scripts moved in the
  59         'config' and 'm4' directories).
  60
  61         <li> SConstruct, libtiff/SConstruct: Added the first very preliminary
  62         support for SCons software building tool (http://www.scons.org/).
  63         This is experimental infrastructure and it will exist along with the
  64         autotools stuff.
  65
  66         <li> port/lfind.c: Added lfind() replacement module.

  74
  75 <UL>
  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:
  79         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=922">
  80                 http://bugzilla.remotesensing.org/show_bug.cgi?id=922</a>
  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.
