[Openmcl-devel] Undeclared free variable CCL::FASL-VERSION

[Gary Byers]

I exported TARGET-FASL-VERSION from the CCL package in r15097.

Until all versions of CCL that ASDF wants to run on incorporate
that change, it (and other code that needs to know this information)
probably has to do somthing like:

(defun ccl-fasl-version ()
   (or (and (fboundp 'ccl::target-fasl-version)
            (funcall 'ccl::target-fasl-version))
       (and (boundp 'ccl::fasl-version)
            (symbol-value 'ccl::fasl-version))
       (error "Can't determine fasl version.")))

Yes, that's a bit awkward.  Consider it penance for referencing an
internal CCL-package symbol.

If anyone finds themselves with a need to do this sort of thing (reference
something internal because there is no public interface), please open a
feature request in Trac.  That'll:

  a) increase the chance that the public interface gets added (or that
     someone will explain that we don't think that there should be a
     public interface in some cases.)
  b) increase the chance that we'll be aware of the fact that someone's
     currently poking around in internals and possibly increase the
     chance that changes to affected internals were made public ("we
     plan to get rid of CCL::RANDOM-INTERNAL-THING soon, use ___ instead.")
