Why did you attach the source code for GNU make? We already have that.

You didn't show us the rule that uses this value of $(OBJS) so it's hard
to help.
If your rule looks something like this:
foo.lib: $(OBJS)
lib /out:$@ $^
or something (I am not familiar with Windows compiler tools).
Instead of this, you can try changing directories and then removing the
$(PATH_OBJ) prefix. For example something like this:
foo.lib: $(OBJS)
cd $(PATH_OBJ) ; lib /out:$(CURDIR)/$@ $(patsubst
$(PATH_OBJ)%,%,$^)
This will greatly reduce the length of your line since you won't have to
include the path to every object in the list.
Of course, this will only help so much; eventually you'll still exceed
the limits of the command line.
At that point all you can do, as far as I know, is create two libraries
instead of one, or else upgrade to a newer version of GNU make and use
the $(file ...) function to generate a file containing the list of
objects and use that with your command.
