[Ecls-list] Latest changes

[Juan Jose Garcia Ripoll]

I have been abroad, and then again ill for several days, and see that there 
are some reported errors in ECL. Ok, I will fix them! But I also found a few 
errors of my own :-) thanks to Edi Weitz's CL-PPCRE package, and have 
committed some changes to the CVS repository. Here's a summary:

* Errors fixed:

  - The PCL relied on the compiler to optimize certain method
    combinations. However, the compiler is not always present, and
    therefore it is safer to use interpreted functions instead.

* Visible changes:

  - No "Bye" message in QUIT.

* ANSI compatibility:

  - WITH-HASH-TABLE-ITERATOR implemented.

  - In DEFGENERIC, only SPACE and SPEED declarations were allowed.

  - The bytecodes compiler did not contemplate the possibility of
    a lambda list with &key and no keyword variables.

  - In MAKE-PATHNAME, values which are supplied (even if NIL), are not
    overwritten by the :DEFAULTS. For instance, (MAKE-PATHNAME :TYPE
    NIL :DEFAULTS "FOO.LISP") => #P"FOO"

This last error is rather important, as it caused problems with DEFSYSTEM.
Have fun!
