Thanks! I'm applying this change:
2000-11-29 Akim Demaille <[EMAIL PROTECTED]>
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!
