New CLISP version

[haible (Bruno Haible)]

Once more, there is a new version of CLISP at the usual place:
ma2s2.mathematik.uni-karlsruhe.de:/pub/lisp/clisp/source .

Excerpt from the change log:

User visible changes
--------------------

* COMPILE-FILE now handles top-level forms as described in CLtL2 p. 90:
  The macroexpansion of a top-level form is considered a top-level form.
  When a top-level form is a PROGN, LOCALLY, COMPILER-LET, SYMBOL-MACROLET
  or MACROLET form, the subforms of its body are considered top-level forms
  too and are compiled separately.
  This allows things like
    (PROGN (DEFCONSTANT X 3141) (DEFUN GET-X () X))
  or
    (PROGN (DEFCLASS SHIP () ()) (DEFUN SHIP-P (X) (TYPEP X 'SHIP)))
  to work.
  Warning: If you want to inhibit this splitting into separate forms (for
  example, because several of the forms refer to the same uninterned symbol),
  you have to use (LET () (PROGN ...)) instead of (PROGN ...).

* X3J13 vote <144> is implemented: New macro DECLAIM.

* X3J13 vote <113> is implemented: The macro LOCALLY is now a special form.

* Fixed a serious bug in the compiler: When compiling functions inline
  whose parameters are special variables, incorrect code could be generated.

* Fixed a bug in the compiler which caused the compiler to crash in some
  rare cases, notably when compiling Garnet-2.2.

* Fixed a bug that prevented the debugger commands DOWN and BOTTOM from
  working on Linux and SunOS.

* Fixed a CLOS bug: Specifying &KEY without &REST in generic function
  lambda lists didn't have the desired effect.

* DEFCLASS supports both :DEFAULT-INITARGS syntaxes.

* DEFGENERIC is more tolerant about invalid declarations.

Portability
-----------

* Added Dynix/ptx Sequent support. Thanks to Esther Davis.

* Added support for RS/6000 CPU and AIX. Thanks to Gabor Herr.

Other modifications
-------------------

* Made the memory allocation and (ROOM), (TIME ...) more virtual memory
  efficient (less paging on Unix and DOS). Thanks to Don Cohen.

* Added Geoffrey Gordon's "LISP tutorial".

* Renamed stdwin.lsp to stdwin2.lsp.

* Miscellaneous documentation updates.
