you can try to fool Stata around with -xtlogit- which is an
algebraically equivalent procedure. If it does not work, you can start
asking yourself whether specifying constraints is a sensible thing to
do statistically (it may well be worth doing from the substantive
point of view, like imposing some sort of symmetry, etc., but it may
lead to some problems with identification, or something of that kind).
