Yes, that is saying that since the rule (what is actually done) for t4 depends on the contents of t2, your makefile setup is not portable to all POSIX implementations of make (in particular, those that implement the "delayed remaking" method such as GNU make). > (Sorry for quoting POSIX on a GNU list.) Eh? The GNU community has historically been quite active in the POSIX standardization process. Paul helped craft the requirements for the delayed remaking method, such that it permits the behavior of GNU make. Philip Guenther
