use *DEFAULT-PATHNAME-DEFAULTS* as current working directory, because it
is set to the initial directory and because it can be updated with SI::CHDIR.
+ Pathname versions are now properly handled and printed. At least for logical
pathnames, because physical namestrings cannot have version numbers.
+ An error is signaled when one tries to print _readably_ a pathname that does
not have a namestring such that parsing this namestring produces the same
pathname. This happens, for instance, with pathnames that do not have hosts,
or that have version numbers and are not logical.
+ Fixes in the CLOS subsystem: ADD-METHOD and REMOVE-METHOD now update the
GENERIC-FUNCTION slot of method objects, and output the right values.
It is now possible to use two nested SYMBOL-MACROLET that define the same
symbols.
LAMBDA-PARAMETERS-LIMIT are both 64. Up to C-ARGUMENTS-LIMIT may be
passed to a function using C calling conventions. If the function is
to retrieve more arguments, (for instance through a &rest variable),
this can be done, but then the arguments have to be pushed on the lisp
stack. This method allows us to raise the CALL-ARGUMENTS-LIMIT up to
MOST-POSITIVE-FIXNUM. From a users point of view, there is no visible
change, excep the fact that a function may receive more arguments.
The function apply() has been replaced with cl_apply_from_stack().
The former took a pointer to the list of arguments. The latter assumes
that the last "narg" elements on the lisp stack are the arguments of
the function.
kept in a single array, "cl_symbols". The translator "dpp" and the
routine SI::MANGLE-NAME, output the right name for any symbol
which is in this array.
Bit fiddling operations with negative fixnums now work.
Remove unportable code of the type va_list d = cs.
Simplify gathering of &rest and &key arguments in compiled code.
growth of the stack and in the way va_arg() arguments can be accessed.
Fix the bytecodes compiler so that it handles toplevel forms properly and
so that it understands LOCALLY.
Split configure.in into configure.in+aclocal.m4 and improve the resulting
tests.
