Sorry, to rehash an old subject, but I'm a few weeks behind in my mail.
Looking through my backlog, however, I do not see the correct description
of the problem; so here goes.

I tried this on both our Locus Distributed System and on Caltech's 4.2 system.
If $cdpath is not defined, I get "Permission denied."  If I do have a cdpath,
I get "no such file or directory."  The problem is that Csh has tried to
do the "cd" relative to each directory in the cdpath and has failed each time.
It then reports the LAST error it encountered.

It seems to me that the best way to report errors in this case would be to
report the FIRST error which is not "no such file."  The "no such file"
message should appear only if EVERY call to chdir() resulted in ENOENT.
