  * libtiff with libjpeg-ipp sometimes produces spurious "Premature end of file" messages. 
 
+== Building ==
+
+In order to build GDAL and libtiff in "IPP compatible" form, it is necessary to define the IPPJ_HUFF macro for the build.  This can be manually accomplished for each.
+
+=== libtiff ===
+
+Add the following in libtiff\libtiff\tiffconf.h:
+
+{{{
+#define IPPJ_HUFF
+}}}
+
+=== GDAL ===
+
+On unix edit GDALmake.opt and add a "USER_DEFS=-DIPPJ_HUFF" macro at the top of the file.
+
+On windows add /DIPPJ_HUFF in the OPTFLAGS macro.
