Consider -B/foo- given that both /foo- is a directory but /foo-cc1 is
the C compiler.  Do we really want to change the semantics of this
admittedly convoluted example?

Or should we perhaps change the treatment of the lack of a trailing
DIR_SEPARATOR from the command-line switch handling to the various
uses, attempting to append DIR_SEPARATOR only if we don't find what we
want without it?

But then comes the question of whether we'd try appending
DIR_SEPARATOR to each component of the search path after searching all
of the search path, or after trying each component?
