Yes, the problem is related to bug #302.  I agree that fix for bug #302
needs some discussion.  On the other hand I think that last reason I gave
(forcing build failure in case of compilation errors) alone justifies
the patch. Concerning bug #302, I would globally replace probe-file and
delete-file by axiom-probe-file and axiom-delete-file and then I would
use whatever host Lisp offers so that axiom-probe-file behaves on
directories the same as on files (and the similarely for axiom-delete-file).

When you speak about "a lot of implications" do you mean that probe-file
is used in many places or that it is used in may different ways?  In the
first case a wrapper called axiom-probe-file would be a perfect solution.
