-# created (!). Since OpenBSD doesn't support LOAD-FOREIGN, this
-# doesn't matter much, since it punts with UNSUPPORTED-OPERATOR
-# instead of not finding the file. But it'd be nice to straighten
-# this out, if only so that sbcl-foreign-test-*.o clutter
-# doesn't pile up in this directory. Maybe some time when I have
-# several test machines at hand to check the behavior of different
