Fix Trac #3823, plus warning police in TcRnDriver

The immediate reason for this patch is to fix #3823. This was
rather easy: all the work was being done but I was returning
type_env2 rather than type_env3.

An unused-veriable warning would have shown this up, so I fixed all
the other warnings in TcRnDriver.  Doing so showed up at least two
genuine lurking bugs.  Hurrah.
