It _doesn't_ work for me in a stripped-down scenario.
$ cat hello.me.in
.p
We're going to run @g@troff.
$ cat Makefile.double-suffix.gnu
SUFFIXES += .me.in
.me.in.me:
sed 's/@g@//' $< >$@
all: hello.me
clean:
rm -f *.me
$ make -f Makefile.double-suffix.gnu
make: *** No rule to make target 'hello.me', needed by 'all'. Stop.
Adding '.me' to the 'SUFFIXES' macro/variable doesn't help.
The following works with NetBSD make ("bmake" on my Debian system) and
GNU Make, but '.SUFFIXES' is unfortunately forbidden by Automake.
$ cat Makefile.double-suffix
.SUFFIXES: .me.in .me
#.SUFFIXES: .me.in
.me.in.me:
sed 's/@g@//' $< >$@
all: hello.me
clean:
rm -f *.me
Note the commented line, corresponding to your original example. _Both_
suffixes must be present. (In the groff build, I think '.in' is already
in 'SUFFIXES', either thanks to "hdtbl.am" or GNU Make or Automake's own
internal pre-definitions.)
