Wait, the above example is about extending automake, but not about rules
which produce multiple output files, right?

For the above, I'd just use (assuming SUFFIXES has already been set)

SUFFIXES += .rc
WINDRES = windres
.rc.$(OBJEXT):
        $(WINDRES) $(WINDRESFLAGS) -o $@ $<

bin_PROGRAMS = hello
hello_SOURCES = hello.c
# probably the following needs to go in a conditional
hello_LDADD = resfile.$(OBJEXT)


Hope that helps.

Cheers,
Ralf
