ooc-980420 & oo2c-1.3.3

[Michael van Acken <KK120y2@mail.lvr.de>]

Only 2 minor bugfixes in the last 2 months.  Not bad.

o Bugfix: Only global procedures can be assigned to procedure
  variables. 
o Bugfix: A statement sequence at the end of the file sent the parser
  into an endless loop.
o The included libtool script has been updated to v1.2.
o Installation will use the libtool script installed on the target
  system.  Only if no libtool is installed, the script included in   
 the oo2c distribution will be used.  This allows to use a patched
  libtool on machines that aren't supported by the standard libtool. 
o RedHat 5.0: Installation problems are caused by garbage collector.
  Get a more recent gc (see file PROBLEMS for URLs), and replace the
  gc subdirectory with it.
o The file KNOWN_BUGS is now part of the distribution; it has 2
  entries at the moment, one of which is just a installation problem.
o All configuration suggestions for the Emacs mode have been    
collected in the file src/tools/emacs/o2-default.el.  For any    
recent version of GNU Emacs the file should compile "as is".  See    
OOCref for details.   
o Adjusted ETA of complex number support to "never".  I don't have   
 the time, nor the motivation, to implement this; on the other  
hand, I still think complex data types are a Good Thing(TM).  In  
short: OOC will never support complex numbers as basic data   type,
unless someone else adds the necessary code to the compiler  
frontend. 
o The texinfo sources and the info files from OOCref-980414 are
  included in the docs directory.  The info files are installed with
  oo2c, but the main info directory, e.g. /usr/info/dir, must be
  adjusted manually to include them.
o File access on our WWW server has improved somewhat.  Instead of 
  a single file index we have a number indices for different 
  directories.  I'll fix the OOC Home Page in the next few days.
