That's weird because it is already there. Are you sure you are using the 
latest gdcm 0.6 (the branch).

Ok I can reproduce the problem. But it make perfect sense, I guess this 
is a stupid problem of dllimport vs dllexport. And maybe jpeg lib is not 
nicely done.

I'll have a look later

Thanks for report, and now I know how to cross compile :)
