I think there's a bug in GNU make version 3.27. I tried to use GNU make because I wanted to use the "-j" option, but the problem was that it didn't run the jobs concurrently. I looked into this in the source a little. Make is picking up the "-j" option fine, but it later resets the value to "1". It looks like make is creating a MAKEFLAGS variable in construct_makeflags, and is then reading that variable as though it were originally in the environment. construct_makeflags always sets the "-j" option to 1 (I assume that's to avoid an explosion of processes). I didn't understand enough of what was going on in the code to know why make processes the variables this way. I don't really think it makes any difference what makefile you use, but here's a teeny one that demonstrates the problem: ----- a: sleep 5;echo toot sleep 5;echo toot ----- Thanks for your attention to this.
