MAKE-PATHNAME ignores version in :DEFAULTS

[Mark Evenson]

​Faré reports:

(defparameter *wild-file*
 (make-pathname :name :wild :type :wild :version :wild :directory nil))

(describe *wild-file*)
(describe (make-pathname :defaults *wild-file*))

which shows that MAKE-PATHNAME ignores the VERSION of the defaults.

Patch to fix root cause of #150

[Mark Evenson]

The patch exposes further problems in how ABCL deals with wild pathname components when ASDF tries to load and compile systems.

r13289 fixes problems with ENSURE-DIRECTORIES-EXIST but there are further problems with ASDF.

[Mark Evenson]

r13290 and r13291 fixed further issues in ABCL's use of Pathname version.

r13294 patched the root cause.

[Mark Evenson]

A little too optimistic

MERGE-PATHNAMES.6
OPEN.ERROR.17

are failing in the ANSI-COMPILED tests.

[Mark Evenson]

With r13296 and r13295, the MERGE-PATHNAMES.* ANSI tests now pass.

[Mark Evenson]

The (the only reason?) why ABCL was sort of working with systems like ASDF even though it had broken usage of the VERSION component was that the Pathname copy constructor always set it to NIL. This constructor is used internally by routines such as MERGE-PATHNAME to avoid sharing structure between its arguments and its results.

The following patch fixes the copy constructor while breaking ASDF loading again. I'm working on figuring out a single patch to fix the failures holistically rather than destabilizing trunk.

r13300 and r13302 (hopefully) establish the correct ANSI behavior.

The newly failing ANSI tests now pass.

(In [13294]) Fix #150: MAKE-PATHNAME ignores version in :DEFAULTS.
