ooc-960402

[acken@informatik.uni-kl.de]

What has changed:
- the TODO list is now part of the distrib in ooc/doc/TODO_List; it
  differs from the version I posted previously in two points:
  o added optimization Range Analysis, together with literature
    reference 
  o added (preliminary) description to the GUI lib; Dirk Vleugels
    volunteered for this job
- optimizers (from Juergen):
  o New: RedundantGates.Mod
    Procedure `Eliminate' removes unnecessary `gate' instructions from
    the intermediate GSA code.
  o DependencyAnalysis.Mod
    Changed the algorithm to follow the possible usage of addresses more
    precisely leading to some more eliminations of gates.
- ANSI-C back-end
  Generating C declarations works, a simple make is implemented; note
  that not a single statement is emitted, and it's likely that it will
  stay this way for the next few weeks 
- plus the usual number of small bug fixes
