[Ecls-list] Problem with pathnames in ASDF in ECL 10.7.1

[Pascal J. Bourguignon]

When loading :alexandria with asdf in ecl 10.7.1, there's a mix up
with pathnames.


Filesystem error with pathname #P"LIBCL:ASDF-SYSTEMS;PACKAGE.LISP".
Either
 1) the file does not exist, or
 2) we are not allow to access the file, or
 3) the pathname points to a broken symbolic link.
   [Condition of type FILE-ERROR]

Restarts:
 0: [TRY-RECOMPILING] Try recompiling package
 1: [RETRY] Retry performing #<ASDF:COMPILE-OP NIL 69316208> on #<ASDF:CL-SOURCE-FILE "alexandria" "package">.
 2: [ACCEPT] Continue, treating #<ASDF:COMPILE-OP NIL 69316208> on #<ASDF:CL-SOURCE-FILE "alexandria" "package"> as having been successful.
 3: [RETRY] Retry SLIME REPL evaluation request.
 4: [*PROCESS-INPUT] Continue reading input.
 5: [ABORT] Return to SLIME's top level.

In the previous versions of ASDF, and I believe it is a strong design
feature of ASDF, it followed the symbolic links (using truename at
some point) to find the files of the system.  Personnally, I wouldn't
mind NOT relying on symbolic links, but a lot of system installations
do, including ASDF-INSTALL and LIBCL.
