I went back to GNU make 3.74 and I can't find any version that behaves
as the manual documents, including 3.8* or current HEAD.  However they
all behave the same way which means that I can't reproduce the problem
described in the gnutls mailing list either.

Maybe my test makefile has a flaw?

#----------
.SUFFIXES:
.SUFFIXES: .x .y .q .r

.x.y: foo.h ; @echo cp $< $@

.q.r: ; @echo cp $< $@
#----------

Then I ran "touch foo.h foo.x foo.q".

Now when I run both "make foo.r" and "make foo.y", it runs the
appropriate suffix rule.
