it seems that the newest version of make contains a built-in implicit rule
looking like this:

%: %.c

That rule seems to be better then going the longer path %.c --> %.o --> %
That's why make chooses it.

I hope this explains it.  By calling -r you get rid of built-in rules
altogether.

Or you can use

.SUFFIXES:

to clear the list of recognized suffixes.  The suffixes are not necessary
as long as you use the pattern rules, not the old-style implicite rules.
