[Openmcl-devel] Another Directory Bug

[wws2 new]

The Clozure version of directory is a real barrier to porting my code from MCL, as a Common-Lisp function it should just work apart from a few tweaks to pathname protocols.  The latest problem is that the Clozure version of the Common-Lisp Function Directory fails to return all volumes on my system.  In particular it fails to return the one where the operating system is located.  (In my case CCL is located on a partition.)  Terminal shows all my partitions of course.

Welcome to Clozure Common Lisp Version 1.4-r13119  (DarwinX8664)!
? (directory "Volumes/*" :directories t :files nil)
(#P"/Volumes/work/" #P"/Volumes/DOS/" #P"/Volumes/play/" #P"/Volumes/public/" #P"/Volumes/plans/" #P"/Volumes/private/" #P"/Volumes/xSpare/")
? 

Doesn't anyone use Directory?

Surely there should be no duplicates to delete in the first place (even if :follow-links is true), and doing so must be beyond the Common-Lisp spec.  The source seems to suggest that the reasons for doing this is extraneous to the common-lisp definition.  What do you language experts think?
