Thanks!  I'm applying this change:

2000-11-29  Akim Demaille  <address@hidden>

        sizeof (struct {char a,b; }) is not required to be 2.
        Reported by Johan Danielsson.

        * tests/semantics.at (AC_CHECK_SIZEOF): Define charchar as an
        array of 2 chars.
        Suggested by Alexandre.

Johan, I think we have fixed all the troubles you faced.  Could you
check that the test suite now runs smoothly?  Thanks!
