It can be enabled locally by passing -DATOMIC_UNCOLLECTABLE as part of
the value of the variable BOEHM_CFLAGS in Mmake.common.  (Although, you
are presumably aware of that.)

As to whether it _should_ be enabled by default for Mercury, AFAIK
no-one has actually tested the effect of enabling it with Mercury and
that would need to done before any decision is made.
