How about if we use a naming convention that the code transformation
tool could pick out?  That is, instead of

  bset_directory (b, current_buffer ? BVAR (current_buffer, directory) : Qnil);

we have something like this:

  b->Directory = current_buffer ? current_buffer->Directory : Qnil;

Here the convention is that the Lisp field names start with
a capital letter.  Almost any naming convention will do.

This is straight C, so the preprocessor would not need to be
used until we have a garbage collector that needs it.
