Hello, Consider the following makefiles: $ cat Makefile MAKEFLAGS+=VAR=foo all: $(info make VAR=$(VAR)) @echo "env VAR=$$VAR" $(MAKE) -C lib $ cat lib/Makefile all: @echo "env VAR=$$VAR" $(info make VAR=$(VAR))
With GNU Make 4.4 and older, the output is: $ make --no-print-directory make VAR=foo env VAR=foo make -C lib make VAR=foo env VAR=foo With GNU Make 4.4.1, the output is: $ make --no-print-directory make VAR=foo env VAR= make -C lib make VAR= env VAR= I have a makefile that depends on VAR being set in the sub-make as in Make 4.4. Was I depending on a bug or undefined behavior or is this a bug in Make 4.4.1?
