Though this may not be the write time I tried to write some routines that
checks the dependencies. It is not at all integrated with the build process,
I just wrote the routines to check dependencies. I am sending it here for a
review to see if the routines do what they are supposed to do (except for
any errors I might have done). Some more routines may also have to be
written to make it useful.

When the attached file is loaded it will go through the lisp files in the
Emacs tree and write two files lisp\dep.lst and lisp\dep.warnings.
