Since adding something to an archive updates the timestamp, you could
use a makefile like the one below. This lists in one place the fact 
that the archive is dependent on all the files. If any files change,
the ones that have changed (this is what $? does) are recompiled and
stuffed back into the archive.

FILES 	=	routine1.c \
		routine2.c \
		routine3.c

stuff.a:	$(FILES)
	cc -c -O $?
	ar rv stuff.a *.o
	ranlib stuff.a
	rm *.o
