Follow-up Comment #5, bug #65759 (group make):
I looked through the code. This is explicitly handled, and ignored, with a
commit message by Roland from 1995 saying only:
commit 636435e5c25d39fc5d52edf936e8e7a410b31b1a
Author: Roland McGrath <rol...@redhat.com>
Date: 1995-03-07 22:31:01 +0000
(decode_switches): If non-option arg is "-", ignore it.
So, I'm not sure why this was done or what the right thing to do is going
forward. Maybe we should be printing a warning. I wonder if it's there
because some makefiles contain recipes like this:
submake:
$(MAKE) -$(MAKEFLAGS)
where, if MAKEFLAGS is empty you get *make -*.
I will think about it.
