[Dcmlib] Error Linking with Static Library gdcm.lib with VC 6.0 --> With gcc4.1, too

[Mathieu Malaterre]

There is not real interest in solving this issue. Those are old
examples. JPEG support is now completely integrated in gdcm (basically
code from those two examples was integrated in the main gdcm code).

sorry for the noise, but you can safely ignore those
