I don't see how this quote pertains to Alexandre's point?
Automake by default declares .SUFFIXES: with no targets:
.SUFFIXES:
This removes all the builtin suffix rules, in all versions of make (this
is portable). Then it adds back a predefined set, like this:
.SUFFIXES: .S .c .dvi .info .o .ps .s .texi .texinfo .txi
These are all the suffixes that can appear in a suffix rule. If a
target looks like a suffix rule but one or both of the suffixes doesn't
appear in this list, it's just a normal target to make.
If you want to create some _NEW_ suffix rules, you have to add back the
suffixes you'll use. If, for example, you want to have a rule that
builds .o's from .f's, you need this:
.SUFFIXES: .f # assuming .o was added already as above
.f.o:
Do some compiles here

No, -r is GNU make only.
