It doesn't I think.  See the attached test (which I'd like to commit in
a follow-up patch, to be merged into maint).  Works with Solaris make,
GNU make, NetBSD make and FreeBSD make.  If that tests doesn't cover the
scenario you have in mind, could you please explain it in more detail, so
that we can write a proper test case for it?

I honestly don't understand what isn't clear yet about the bug (which
BTW I see as a limitation rather than a "real" bug).  Could you please
elaborate a bit more on this?
