Re: [armedbear-devel] Change in merge semantics which fixes loading CFFI

After extensive testing and refactoring, I have pushed a series of
changes (from [r14176][] through [r14179][]) to trunk that should,
among other things, finally fix the issues associated with loading
CFFI.
To affect the fixes, I have introduced a slight change
in the merge pathname semantics in [r14178][], which I described
in the Manual by the following text:
When merging pathnames and the defaults point to a JAR-PATHNAME,
we set the DEVICE of the result to :UNSPECIFIC if the pathname
to be be merged does not contain a specified DEVICE, does not
contain a specified HOST, does contain a relative DIRECTORY, and
we are not running on a MSFT Windows platform.  The intent of
this rather arcane sounding deviation from conformance is so that
the result of a merge won't fill in a DEVICE with the
wrong "default device for the host" in the sense of the fourth
paragraph in the CLHS description of MERGE-PATHNAMES (the
paragraph beginning "If the PATHNAME explicitly specifies a host
and not a device").  A future version of the implementation may
return to conformance by using the HOST value to reflect the type
explicitly.
Additionally TRUENAME on non-Windows now fills in the DEVICE component
with :UNSPECIFIC, but this is conforming behaviour.
I will close the relevant tickets when I get a chance (and no one
has proved me a liar in the meantime).
Comments, criticisms, usage reports (especially of the "Yay!  CFFI
works now!" variety), solicited.
First, when loading CFFI I get that ABCL-ASDF package is
undefined. After loading abcl-asdf system, I get:
