This changeset accientally contains changes to file
sql/src/server/sql_parser.mx that should have gone into a seperate checking
/ changeset:

"
Refined my earlier fix "fixed (restored) order_by over union_all"
(http://dev.monetdb.org/hg/MonetDB/rev/35ebc65eb74c):
we now also (re-)allow ORDER BY over EXCEPT & UNION .

Note. though, that (as also in Feb2010 and most probably earlier releases,
MonetDB incorrectly ignores ORDER BY over UNION, EXCEPT & INTERSECT.
See also Bug 2606 (http://bugs.monetdb.org/2606)
"
