I agree that shouldn't be necessary anymore (and if it is, we'll find out soon enough). > I'm on the fence about removing the "touch $@" from the rule building static > libs.

Both do set fine-grained > timestamps: Please see the commit message for 826eff57c4c: the issue seems to arise only with specific combinations of software, in particular with non-Apple versions of "make" (although maybe later Apple builds have fixed make's failure to read sub-second timestamps?). That's a relatively recent hack, and I'm very hesitant to conclude that we don't need it anymore just because you failed to reproduce an issue locally. It very possibly isn't a problem in a meson build, though, depending on how much meson depends on file timestamps. regards, tom lane
