Need for DLLINIT in Makefile.shlib

I am curious why Cygwin needs DLLINIT in Makefile.shlib, and Win32
doesn't:

# Cygwin case
$(shlib) lib$(NAME).a: $(OBJS) $(DLLINIT)
$(DLLTOOL) --export-all $(DLLTOOL_DEFFLAGS) --output-def $(NAME).def $(OBJS)
$(DLLWRAP) -o $(shlib) --dllname $(shlib) $(DLLWRAP_FLAGS) --def $(NAME).def $(OBJS) $(DLLINIT) $(SHLIB_LINK)
$(DLLTOOL) --dllname $(shlib) $(DLLTOOL_LIBFLAGS) --def $(NAME).def --output-lib lib$(NAME).a

$(DLLINIT): $(DLLINIT:%.o=%.c)
$(MAKE) -C $(@D) $(@F)

endif # PORTNAME == cygwin

else # PORTNAME == win32

# win32 case
$(shlib) lib$(NAME).a: $(OBJS)
$(DLLTOOL) --export-all $(DLLTOOL_DEFFLAGS) --output-def $(NAME).def $(OBJS)
$(DLLWRAP) -o $(shlib) --dllname $(shlib) $(DLLWRAP_FLAGS) --def $(NAME).def $(OBJS) $(SHLIB_LINK)
$(DLLTOOL) --dllname $(shlib) $(DLLTOOL_LIBFLAGS) --def $(NAME).def --output-lib lib$(NAME).a

endif # PORTNAME == win32

The only difference I see is that Cygwin uses $(DLLINIT) while Win32 does
not. Is that correct? Why?

Both set DLLINIT in their makefiles:

DLLINIT = $(top_builddir)/src/utils/dllinit.o

Could they be merged into a single snipped of code?
