CLISP 2.28 pretest

[Sam S. <sd...@gn...>]

please get the current CVS sources and test them.
unless bugs are reported, this will become 2.28.

[The Lisp Pretty Printer implementation is not perfect yet.
 PPRINT-LOGICAL-BLOCK does not respect *PRINT-CIRCLE*,
 *PRINT-LENGTH*, &PRINT-LEVEL*, and *PRINT-LINES*.
 this will come in the next version, unless this release will be held up
 by other bugs, or ... dunno.]

Important notes
---------------

* All .fas files generated by previous CLISP versions
  are invalid and must be recompiled.

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

* ANSI CL functions MAKE-LOAD-FORM and MAKE-LOAD-FORM-SAVING-SLOTS
  are implemented.

* ANSI CL pretty printer (chapter 22.2) is implemented.
  In particular,
    variables     *PRINT-LINES*, *PRINT-MISER-WIDTH*, *PRINT-PPRINT-DISPATCH*,
    macro         PPRINT-LOGICAL-BLOCK,
    local macros  PPRINT-EXIT-IF-LIST-EXHAUSTED, PPRINT-POP
    and functions PPRINT-DISPATCH, COPY-PPRINT-DISPATCH, SET-PPRINT-DISPATCH,
                  PPRINT-FILL, PPRINT-LINEAR, PPRINT-TABULAR, PPRINT-TAB,
                  PPRINT-NEWLINE, PPRINT-INDENT
  are implemented.  See the impnotes for details.

* The functions WRITE and WRITE-TO-STRING now accept :LINES, :MISER-WIDTH
  and :PRINT-PPRINT-DISPATCH keyword arguments.
  This change requires recompilation of all .fas files.

* Support Cygwin's "/cygdrive/drive/path" pathname symtax on Win32.

* New macro EXT:FCASE which allows specifying comparison function in CASE.

* Fixed a bug: LDIFF now handles dotted lists correctly.
