Are there other situations where Make uses "foo/" and expects

It's pretty much any situation where Make looks for file names that the user specifies. As a trivial example, the Makefile rule:

foo/:; mkdir -p $@

should fail if "foo" exists as a regular file, since Make will invoke mkdir and mkdir will fail. If Make strips the trailing / before testing the existence of "foo", Make will incorrectly skip the mkdir and so will not guarantee that foo/ is a directory.
