This is because there are two deviations in GNU make compared to other make implementations and your script only tests for one of them. To test for the other deviation, you could use this script: printf 'A = immediate\nB := b\nB += $A\nA = delayed\nall:\n\techo '\''$(B)'\''\n' | $MAKE -s -f - smake prints: smake: WARNING: Nonportable ':=' assignment found for macro 'B' in line 2 col 4 of 'Standard in' b delayed bmake prints: b delayed and gmake prints: b immediate As you see, smake and bmake fully agree and the deviating behavior from gmake never should have made it into the standard. In special: If the gmake documentation would have clearly pointed to it's deviating behavior, I would have protested against https://www.austingroupbugs.net/view.php?id=330 When https://www.austingroupbugs.net/view.php?id=330 was discussed in the teleconference. During that teleconference, I was assuming, gmake was aligned with the behavior of other make implementations like smake and bmake. Note that the change in bmake regarding the expansion of := macros at use time (see your test script) has been introduced after 2015, which is years after https://www.austingroupbugs.net/view.php?id=330 was closed with a wrong decision. Also note that the tool people from netbsd yesterday clearly judged that the deviating gmake behavior for += tested with the script from this bugnote is seen as a bug by them.
