Details:

In the attached archive there is a Makefile that contains 3 rules:

lib%.a : %.def %.o
        $(DLLTOOL) $(DLLTOOL_FLAGS) --output-lib $@ --def $(srcdir)/$*.def
        $(AR) r $@ $*.o
        $(RANLIB) $@

lib%.a: %.def
        $(DLLTOOL) $(DLLTOOL_FLAGS) --output-lib $@ --def $<

lib%.a: %.o
        $(AR) rc $@ $*.o
        $(RANLIB) $@

In versions of make prior to 3.81, the first rule was used for creating
import libraries that were comprised of both .def and object file.  In
version 3.81, the first rule is skipped and the second rule is used, as a
result, the exported functions and definitions in the object files are not
included in the import library.
