Hi Carl; please do not reply to digests. You should use a decent mail
client that can break a digest out into its constituent mails then you
can reply to the individual mail you care about.
And, you should not top-post. And, you should never include the entire
post you are replying to.
And in this case, you aren't replying to ANYTHING in the digest that I
can see, so really you should have just started a new mail rather than
replying in the first place.
Really just about everything that could be wrong with this email, is
wrong... which is probably why you didn't get a response.
The answer is there's nothing very unique about this. It's just the
same as writing:
default:
@echo "blah blah"
%:
@echo "blah blah"
(you can see this by using make -p and examining the database). The "%"
is a match-anything pattern (see the GNU make manual), so any target
make wants to build that is not matched by any other rule, can be
matched by this one.
