CHANGES to libtiff-3.7.0 : jD Gascuel, 2004-11-05 :

  - To enable compilation with a <<modern>> compiler (aka MSVC++ 7.1),
    I had to twick a bit the source here and there, eg. adding casts
    on allocated space before store to its pointer.
    
  - Mixed together tif_config.h and tiffconf.h, and twick a bit the
    compilation flags to get support for LZW, TIFF, and JPEG from Qt.

CHANGES to libtiff-3.7.1 : jD Gascuel, 2005-01-14 :

  - Downloaded brand libtiff-3.7.1.zip.

  - Have to redo the same twicks (casting CLAMP() to (uint16), to avoid
    data loss warnings, casting _TIFFmalloc() to the appropriate pointer type,
    changing pow() to powf() in tif_pixarlog.c.

  - Have to fix bugs in tif_win32.c Win32WarningHandler() and 
    Win32ErrorHandler() that messed-up with uninitialized szTmp variable.

  - Have to fix tif_getimage.c TIFFReadRGBAImageOriented() to initialize
    emsg to "no error" in case TIFFRGBAImageBegin() returned an error without
    setting it (eg when reading 16 bits LAB or CYMK).
