    REPEAT BY:

Try to link a shared library.

    SAMPLE FIX/WORKAROUND:

I tried to fix it but with GNU configure I don't even know where to start. 
Give me a hint and I give it a try.

1) use -aI instead of -I - but then the whole of PolyORB is recompiled.

2) use --enable-shared when reconfiguring might help es well - but currently 
it is broken so I can't confirm that.
