  * Test/Makefile building now depends on the one of libgdcm.so
      * src/gdcmHeader.cxx and gdcm.h are now OB (undefined length encoded
        pixel data) aware which enables finding the address (offset) of
        the pixel data of JPEG encoded DICOM files. This leaves only a single
        file in the testSuite whose pixel data address (offset) is unknown.
      * python/testSuite.py changed accordingly. --- Frog
