Thank you, I got valuable feedback: The 't2' prerequisite of 't4' considers differently the timing internals of the 'make' execution and re-executions. Practically 'make' refers to prerequisites in case of include file remakes in regards to pre and post update differently than I thought. Could imagine some syntax extension in 'makefile' for finer control of re-executions.
Nevertheless, this got good enough for now with forcing a re-execution: $ diff t1.bak t1 1c1 < t2: t1 t3; m4 -D n=t7 t3 > $@ --- > t2: t1 t3; m4 -D n=t7 t3 > $@; exit 129 $ make -d -r -R t10 GNU Make 4.4.1 Built for x86_64-pc-cygwin Copyright (C) 1988-2023 Free Software Foundation, Inc.
