Thanks, now applied to trunk and 4.1.  The patch doesn't apply directly
to earlier branches because they used TREE_LISTs rather than VECs
for CONSTRUCTORs.  A straight-forward conversion would introduce a linear
walk over the list to get to the last element, which is probably not
acceptable.  I'm leaving this PR as a 3.4 and 4.0 regression for now.
