Patch by Gerd Moellmann to turn old-style into new-style eval-when's in the PCL code base.
Patch by Gerd Moellmann to remove unused functionality from macros.lisp.
Slightly frobbed patch from Gerd Moellmann that eliminates the function EXTRACT-DECLARATIONS in favour of SYSTEM:PARSE-BODY. This also removes the ability for macros to expand into declarations, which isn't allowed anymore by ANSI CL.
Huge patch by Gerd Moellmann that removes PCL::ITERATE and PCL::GATHER* in favor of normal CL constructs. In a similar vein to SBCL, this patch also replaces all uses of #'(lambda ...) by just (lambda ...), and removes now-dated looking quotes in front of self-evaluating objects, like keywords and t/nil. The patch has been slightly frobbed by me, to correct a couple of slight oversights, and make more effective use of the loop facility in a number of places.
Patch by Gerd Moellmann to remove PCL's variant of once-only, replacing it by the version already present in CMUCL.
Slightly mangled patch by Gerd Moellmann to remove PCL's own version of destructuring-bind in favour of the ANSI CL version already in CMUCL.
Change toplevel PROCLAIMs to DECLAIMs.
Remove all #+ and #- conditionals from the source code. What is left is essentially Common Lisp except for explicit references to things in CMUCL specific packages.
Revision 1.12 for FIND-CLASS broke the PCL build process. This is a better fix (suggested by Douglas) in that FIND-CLASS-CELL as called from FIND-CLASS is not allowed to produce any side effects. This restores the build process and lets (find-class :x nil) => NIL as relied on by some codes.
fix find-class (when called with nil second arg) to be silent even if the supplied class name is invalid.
Further cleanup of the code now that the :SETF feature is assumed standard.
Add CMUCL style file-comments; from Peter Van Eynde.
Fix a programming error that was flagged by Python unreachable code warning.
This set of changes enables the use of forward referenced classes in PCL. The problem was(is) that the wrapper object needed to connect the Lisp type system to PCL classes doesn't exist until the forward-referenced-class is defined. At that time all the subclasses of it are initialized and wrappers attached. In the meantime, the actual forward referenced class is an instance of pcl::forward-referenced-class and any subclasses are pcl class instances with most slots nil. The fix herein arranges for UPDATE-LISP-CLASS-LAYOUT to also set the lisp:class-name and use (setf lisp:find-class) to connect the new layout to the Lisp class system. An undesired consequence of this is that DEFCLASS can't return a valid class object unless all superclasses are defined. This shouldn't be a real problem as the classes can't be used in the intermediate state, but the HyperSpec says DEFCLASS returns a class object. We return a valid class object or NIL.
This commit brings the PCL repository up to release 17f and also includes the changes in the X86 1.03.7 kit. Although the 1.03.7 changes were already in the repository, the other files appear to be of early vintage and do not work with a 17f system. Hopefully all is correctly synched now.
September-16-92-PCL-e has been incorporated into the CMUCL sources thanks to Rick Harris.
This is September 92 PCL.

This is March-92-PCL-2a.
Merged with latest PCL version.
