Changes to make it work:
Please run diff against the .mo files I fixed because i haven't put all the changes here.

Algorithm.mo:
- should import:
  protected import OpenModelica.Compiler.Absyn (because of a return type)
  + this doesn't happen in RML as the types are inferred.

Builtin.mo:
- Types.UNBOUND should be: Types.UNBOUND()

Ceval.mo:
- ceval_range_real2:
  Values.REAL(start) :: l instead of Values.REAL(start::l)
- ceval_range2
  Values.INTEGER(start :: l) should be Values.INTEGER(start) :: l
- ceval_function
  Prefix.NOPRE  should be Prefix.NOPRE()
  Inst.TOP_CALL should be Ist.TOPC_CALL()
- ceval_interactive_functions and all the others
  Types.UNBOUND should be Types.UNBOUND()

Connect.mo:
- merge:
  EQU(cs)::ss_1  instead of EQU(cs::ss_1)
  FLOW(cs)::ss_1 instead of FLOW(cs::ss_1)

DAELow.mo:
- print_equation_no:
  true = print_equation(eq); should be print_equation(eq);
- print_equations:
  true = print_equations(rest, dae) should be print_equations(rest, dae);
  true = print_equation_no(n, dae)  should be print_equation_no(n, dae);
- add_variables_to_env:
  SCode.RW should be SCode.RW()
  SCode.CONST should be SCode.CONST()
  Types.UNBOUND should be Types.UNBOUND()
	
Env.mo:
- tree_new: should be:
  matchcontinue() case () then ... or
  out_bintree := TREENODE(NONE, NONE, NONE);

Inst.mo:
- mktype:
  all the then (Types.T_XXX(xx), somep) should be ((Types.T_XXX(xx), somep))
- compatible_arraydim:
  DIMINT(x::l) should be DIMINT(x)::l
- elab_arraydim_type:
  SOME(DIMINT(i) :: l) should be SOME(DIMINT(i)) :: l
- elab_arraydim_decl:
  SOME(DIMEXP(Exp.INDEX(e),NONE) :: l); should be SOME(DIMEXP(Exp.INDEX(e),NONE)) :: l;  

Interactive.mo:
- replace_public_list:
  should be Absyn.PUBLIC(newpublst)::rest_1 instead of Absyn.PUBLIC(newpublst::rest_1)
- delete_public_list:
  should be Absyn.PUBLIC(newpublst)::rest_1 instead of Absyn.PUBLIC(newpublst::rest_1)
- replace_equation_list:
  should have Absyn.EQUATIONS(newpublst) :: rest instead of 
              Absyn.EQUATIONS(newpublst :: rest)

Static.mo:
- n_dim_array should return:
  ((Types.T_ARRAY(Types.DIM(NONE),t_1),NONE)); instead of
  (Types.T_ARRAY(Types.DIM(NONE),t_1),NONE);
- elab_code_type should return:
  (of what is now) 

VarTransform.mo:
- empty_replacements: should be:
  matchcontinue ()
  case () ....
