'ci -l' will leave your source file intact and keep 'make' happy. Assuming
you want to save disk space tho', do a 'ci filename', then a 'touch
filename' so that make will see a datestamp to calculate dependencies
from. Then something like:

.c.o:
	-rm -f $<
	co $<
	$(CC) -c $<         # add options to flavor
	rm & touch $<       # or just echo ""> $< - just uses 1 char.

to create your .o's, and then:

target:	dependencies
	optional rm's
	cc -o $@ dependencies $(OPTIONS)
	optional chmod's
	(rm & touch) or echo> your dependencies # NOT a good idea unless
						# you expect to re-compile
						# everything everytime
						# (of course you could
						# 'ar r' them)
	optional mv your target to destination dir and 'ln -s' to it
