Kind of. It is not quite a "local file". Cf:

`---- (info "(emacs)Directory Variables")

This too, normally "local variables" are not attributable to
directories, are they?

It seems that it's a dired's problem rather than cc-mode's.
Eli> Or something else?
My expectation was that I could specify a local-variable setting
common to all the files from the directory in question. And
actually it does work. The only problem is that it breaks the
dired buffer.

Because there is no appropriate means to impose a reasonable
condition. Just the "nil" or a major mode name. It may happen
that I do not know the a-priori mode; actually it is mode that I
would like to set.
After all, I've found a workaround; but I believe the feature
would be more useful if it could be restricted to '-' files only
(i.e. only to those which normally can contain
"Local variables:"):
