mzn-fzn does not appear to function the same as the minizinc
executable.
I've attached a model with which the minizinc executable included in
the upstream release works, but which fails using mzn-fzn:
$ mzn-fzn color.mzn
unknown file:
MiniZinc: type error: assignment value for `Bing' has invalid type-inst:
expected `COLOR', actual `int'
=====ERROR=====
