 2-Mar-2010  GBM.DLL 1.65
             * Fix buffer overrun in ILBM HAM6 encoder
             * Fix some compile errors on new GCC 4.4.2 (Linux x86/x64)

             * JPEG codec:
               - Update to IJG 8a
               - Reinstate IJG change that allows a broader range of DC table symbols in huffman 
                 decoder to support loading of PhotoPaint created JPEGs (jdhuff.c). It was
                 implemented in GBM.DLL 1.62 but got lost during update to IJG 7 library.

               - Fix local vs. global color palette handling when reading multipage images
                 (global palette overwritten in multipage images where images before the requested
                  had a local palette but the requested did not)
