I don't think it does. In fact, we are actually still calling it
after we're done with the ada_convert_actuals:

  if (current_language->la_language == language_ada)
    ada_convert_actuals (function, nargs, args, &sp);

  {
    int i;
    for (i = nargs - 1; i >= 0; i--)
      {
        [...]

        args[i] = value_arg_coerce (args[i], param_type, prototyped);

        [...]
      }

I am just wondering whether this is actually useful at all or not.
It depends whether value_arg_coerce covers some cases that the Ada
routine doesn't and yet needs. That's on my end to check. Worst that
would happen is that I would call the C routine from the Ada one.

Should I proceed with my proposal?
