No. You were right originally. The tests do need to $sleep. Please commit your patch with all the sleeps in it (to maint), but please also fix the wrong comments. My thinko was the following: given targets A -> B -> C, and A is out of date, after make updates A, it checks the time stamp again, even iff it knows it has decided to update A. When that time stamp is the same as B, it won't update B. This sequence shows the issue with high probability, the second 'make' often won't update B nor A again: cat > Makefile <<EOF A: B; touch A B: C; touch B C: ; touch C EOF rm -f A B C; make; rm -f C; make Introducing sleeps in aclocal, autoconf, or automake would be a serious usability issue; I need to avoid falling into that misconception of mine again. Thanks for being persistent. Cheers, Ralf
