    I have started to build InterViews 2.3 (coming with X11.R2)
    on our SUN-3:s under SunOS 3.5 with AT&T cfront 1.2.1. So far,
    no good.

This is a bug in cfront that is tickled by InterViews.  As you
correctly point out, the problem is in expand.c.  Here are the
cdiffs.

  xxx:
  	switch( ee->tp->base ) {

  	return( val );

  	return( val );
