Some notes on using "5/1/90  May Day PCL (REV 3)" with KCL and AKCL.

1. KCL will try to load the PCL file "init" when it starts up,
   if you rename the files as is mentioned in defsys.lisp and the 
   currect directory is the one containing PCL.  I suggest that
   you do not rename any file except maybe "defsys", and also 
   that you change the (files-renamed-p t) to (files-renamed-p nil) 
   in defsys.lisp.

2. Do not comment out the file kcl-patches.lisp, even if you are
   using AKCL.  It contins a patch to make compiler messages more
   informative for AKCL, and also sets compiler::*compile-ordinaries*
   to T, so that methods will get compiled.

3. While fixup.lisp compiles, there will be a pause, because 
   KCL's compiler is not reentrant, and some uncompiled
   code is run.  If you want, you can change the form
   (fix-early-generic-functions) to (fix-early-generic-functions t)
   in fixup.lisp to see what is happening.

4. If you want, you can apply the changes in kcl-mods.text
   to your KCL or AKCL to make PCL run faster.  The file kcl-mods.text
   is different from what it was in versions of PCL earlier than
   May Day PCL.  If you do not make these changes, or if you made 
   the old changes, things will still work.

5. If you are using AKCL, and you previously used the kcl-low.lisp
   file from rascal.ics.utexas.edu, you should not use it this time.
   The kcl-low.lisp that comes with May Day PCL works fine.  (If you
   insist on using an old version of kcl-low.lisp, you will need to
   use an old version of the KCL part of fin.lisp as well: this is
   what is done for IBCL, by the way.) 

6. I recommend that you use AKCL version 457 or newer rather than using
   KCL or an older version of AKCL, because there are some bugs in KCL
   that cause problems for May Day PCL.
