r7865: changed pidl to take a "const void *" instead of a "void *" for the
structure in ndr_push_*() and ndr_print_*(). The push and print
functions really should not modify the structure.

metze, to make this work I had to change your spoolss hand
marshaller. Can you please check it is OK? I think that the IN and OUT
sides of that function are not ever called on the same structure, so I
think that attempt at remembering the value by assigning to
r->in._offered was not doing anything anyway, but please correct me if
I have misunderstood it.

If you really do need to remember something on those structures I'd
suggest the ndr_token_store() and ndr_token_retrieve() functions,
which are used by pidl for just this sort of thing.
