In the abstract, I don't think we should use cp_convert here -- but,
then again, we shouldn't really use build_c_cast either.  We should use
some low-level routine which just assembles the right thing, without
doing any semantic checking -- both to avoid any possible error
messages, and to save the expense of checking for errors we know cannot
be there.

However, that's all in the abstract; I think the current patch is
definitely an improvement (fixes a bug!), and I'm not sure there's an
easy way to do the abstractly more right thing, so this patch is OK.

Thanks,
