Freshly committed to CVS...

# Xmas fixes:

  - The reader was not able to interpret RANDOM-STATE objects.

  - The routines in the pretty printer now check the type of the arguments.

  - When parsing a physical pathname, version is NIL unless the pathname
    has a name or a type components, in which case version is :NEWEST.

  - Support for binary streams of arbitrary byte size. By default, binary
    streams are written with an octet as header, which is used to determine
    the actual length of the file. However, if you pass the argument
    :use-header-p = NIL to the function OPEN, the header is not used and
    instead the size in bits of the stream element type is rounded to a
    multiple of 8 (M. Goffioul)

  - The implementation of (SETF VALUES) now produces the right result
    when there are nested (SETF VALUES) forms.

  - DEFGENERIC now signals a PROGRAM-ERROR when the syntax is incorrect.

  - The sequence functions now also accept class objects.

  - DESCRIBE takes an additional (in ECL optional) argument denoting the
    stream to which the description is written (M. Goffioul)

  - Important fixes in how arrays are printed with *print-readably* = T.
    Displaced bitvectors now print properly. (M. Goffioul)

  - SETF-functions can now be traced.

  - In PATHNAME-MATCH-P, mask's missing components become :WILD.

  - A physical namestring without file name/type has now version NIL.
    Otherwise version defaults to :NEWEST. This ensures that directory
    names have version set to NIL.

  - The constants in the code created by COMPILE are now EQ to those in the
    original forms.

  - FIND-METHOD checks the validity of the specializers list.

  * The indentation value in PPRINT-INDENT is a real number. We round it 
to the
    nearest integer.

  * PRINT-UNREADABLE-OBJECT always outputs a space before the identity and
    after the type, even if the forms have been omitted.

  * PPRINT-LOGICAL-BLOCK only accepts strings as :PREFIX and :SUFFIX 
    and these strings need not be simple.

  - All non graphic characters now have a name "A~D" where ~D is the 
    code in hexadecimal form.

  * The code for handling *PRINT-LINES* was broken.

  - WRITE now accepts the keyword arguments :LINES, :MISER-WIDTH,

  * *PRINT-LEVEL* and *PRINT-LENGTH now affect printing of structures and
     instances, as well as PPRINT-LOGICAL-BLOCK.

  * In format directives, a negative value of "minpad" is converted to zero.

  * PPRINT-LOGICAL-BLOCK now includes support for printing circular
    structures when *PRINT-CIRCLE* = T.

  - FLOAT-PRECISION now really returns the number of siginificant digits
    in a denormalized float.

  - PPRINT-TAB did not compute the tab positions properly in any case.

  - "~<~>" removed all padding when the line length exceeded the minimal
    number of columns.

  - FORMAT now signals an error (as per ANSI when a format string
    mixes ~<...~:;...~> with ~W, ~I, ~_, ~<...~:> or ~T.

  - DOCUMENTATION now works on generic functions and methods.

  - Improved initarg checking in SHARED-INITIALIZE, REINITIALIZE-INSTANCE,
    Now the keyword arguments of the applicable methods are considered to
    be valid initargs (ANSI 7.1.2)

# MOP compliance:

  - ADD-METHOD is now a generic function and implements most of the 
protocol in
    the specification except for the calls to ADD-DIRECT-METHOD, because 
we do
    not have specializer objects, and for the call to
    COMPUTE-DISCRIMINATING-FUNCTION because of the differences in the 
    calling protocol.

  - Implemented all of the generic function initialization protocol 
    (RE)INITIALIZE-INSTANCE specializations. Generic functions can now be
    redefined and there are better checks to ensure the consistency 
between the
    lambda lists of a generic function and it methods.



  - Changes preceded by (*) apply only when ECL is configured with CMU CL's
    format and pretty printing routines (configure flag --with-cmuformat).
