FWIW, Chisheng Huang sent the following test case to me in private.  I
hope he doesn't mind me posting it here.

1. In a Unix shell:

   mkdir /tmp/systems
   cat /dev/null > /tmp/systems/v.asd

2. In CMUCL (mine is CMU Common Lisp CVS snapshot 2003-12):
   CL-USER> (setf (logical-pathname-translations "v")
                  '(("**;*.*" "/tmp/**/*.*")))

   (("**;*.*" "/tmp/**/*.*"))
   CL-USER> (MAKE-PATHNAME :DEFAULTS "v:systems;"
                  :VERSION :NEWEST
                  :NAME "v"
                  :TYPE "asd"
                  :CASE :LOCAL)
   #.(logical-pathname "V:SYSTEMS;v.asd")
   CL-USER> (probe-file *)
   NIL
   CL-USER> (probe-file #.(logical-pathname "V:SYSTEMS;v.asd"))
   #p"/tmp/systems/v.asd"
   CL-USER> 

So, I think what is happening is the make-pathname with a logical path
and :case :local, is preserving the case of everything, including the
uppercase parts of the logical path.

Perhaps the right thing is to convert any lower case parts to upper
case when the pathname is a logical pathname.

I have not yet examined the CLHS to see what it says about this.
