  45         <LI> Added GNULDdso target and switched linux and freebsd to use it.
  46         <LI> tools/Makefile.in: Modified to install properly on SGI.
  47         <LI> configure: Fixed DSO test for Linux as per patch from
  48           Jan Van Buggenhout <chipzz@Ace.ULYSSIS.Student.KULeuven.Ac.Be>.

  58
  59         <LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
  60         as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
  61         from vandrove@vc.cvut.cz.
  62
  63         <LI> Modified tif_packbits.c decoding to avoid overrunning the
  64         output buffer, and to issue a warning if data needs to be
  65         discarded.  See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
  66
  67         <LI> Modified TIFFClientOpen() to emit an error on an attempt to
  68         open a comperessed file for update (O_RDWR/r+) access.  This is
  69         because the compressor/decompressor code gets very confused when
  70         the mode is O_RDWR, assuming this means writing only.  See
  71         bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
  72
  73         <LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
  74         of EXPAND1D() as per bug 11 (from Roman).
  75
  76         <LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
  77         cygwin compatibility.
  78
  79         <LI> Applied patch from Roman Shpount to tif_fax3.c.  This seems to
  80         be a proper fix to the buffer sizing problem.  See
  81         http://bugzilla.remotesensing.org/show_bug.cgi?id=11
  82
  83         <LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
  84         downsampling.  http://bugzilla.remotesensing.org/show_bug.cgi?id=10
  85         Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
  86         bug and proving the patch.
  87
  88         <LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
  89         we are done access data thanks to bug report from:
  90         Michael Eckstein <eckstein@gepro.cz>.
  91
  92         <LI> tif_open.c: Don't set MMAP for O_RDWR files.
  93
  94         <LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
  95         so that files opened for update can be strip chopped too.
  96
  97         <LI> tif_read.c: fixed up bug with files missing rowsperstrip and
  98         the strips per separation fix done a few weeks ago.
  99
 100         <LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
 101         SAMPLEFORMAT_COMPLEXINT.
 102
 103         <LI> index.html, bugs.html: added bugzilla info.
 104
 105         <LI> tif_read.c: fix subtle bug with determining the number of
 106         rows for strips that are the last strip in a separation but
 107         not the last strip of all in TIFFReadEncodedStrip().
 108
 109         <LI> Applied 16/32 bit fix to tif_fax3.c.  Fix supplied by
 110         Peter Skarpetis <peters@serendipity-software.com.au>
 111
 112         <LI> Modified tiffio.h logic with regard to including windows.h.  It
 113         won't include it when building with __CYGWIN__.
 114
 115         <LI> README: update to mention www.libtiff.org, don't list Sam's old
 116         email address.
 117
 118         <LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
 119         one tile/strip images with an offset, and byte count of zero. These
 120         could be "unpopulated" images.
 121
 122         <LI> tif_win32.c:  Applied patch to fix overreads and ovverwrites
 123           caught by BoundsChecker.  From Arvan Pritchard
 124           <arvan.pritchard@infomatix.co.uk>  (untested).
 125
 126         <LI> tif_getimage.c:  Applied patch to silence VC6 warnings.  From
 127           Arvan Pritchard <arvan.pritchard@informatix.co.uk>
 128
 129         <LI> tif_lzw.c:  Applied patch to silence VC6 warnings.  From
 130           Arvan Pritchard <arvan.pritchard@informatix.co.uk>
 131
 132         <LI> libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
 133         Leonard Rosenthol <leonardr@lazerware.com>.  May interfere
 134         with correct building on older systems.  If so, please let me know.

 144
 145         <LI> tools/rgb2ycbcr.c: fixed output strip size to account for vertical
 146         roundup if rows_per_strip not a multiple of vertical sample size.
 147
 148         <LI> tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.
 149
 150         <LI>  Modified tiff2bw to ensure portions add to 100%, and that
 151          white is properly recovered.  See bug
