What that means is after the remote data module source code has been
generated, edit all the functions in the ...Impl.cpp source file that
contain:

    *Value = IProv;

so that they read:

    *Value = (IProvider*)IProv;

Some day Borland may see fit to fix this problem.  I was hoping it would be
fixed in update 2; no such luck.  Perhaps they're not aware of the problem?
Or perhaps they don't know how to fix it?
