  You have to link the reg_t hash_map (to briefly promote ML notation here ;-)
implementation, which is contained in "src/scicore/reg_t_hash_map.c". (It's
not really a general-purpose hash-map, though, but never mind that... I
honestly have no idea what to call it; it really works as an interning map
mapping anything stored in it to the smallest unused natural number.)

  Here, we actually just use it to implement a set, which keeps track of all
referenced objects during garbage collection (in lieu of reachability flags).
