I got the toy.cpp program from Chapter 4 of the tutorial to compile, after
one change to line 359  from
   return ConstantFP::get(Type::DoubleTy, APFloat(Val));
to
   return ConstantFP::get(APFloat(Val));

Now to compare it in detail with the much smaller program I've got and
maybe I'll figure out what's wrong with my call to
ExecutionEngine::create.
