Well, Simon Taylor committed his change to add `make' support to the
compiler, and that code has nested modules in it.  So if I add nested
modules to the rest of the compiler, I won't be adding a new problem;
at worst I'll be exacerbating an existing one.

The problem with parallel makes and nested modules does need to be solved.
But I'll commit my change to use sub-modules first.  The cost of keeping
it uncommitted and merging in everyone elses changes is very high for this
change.
