When resolving a line continuation $\<newline>, it normally resolves to $<space>, then to blank. There is a corner case in make 4.2.1 where it seems to resolve to the literal $ character instead. I have the following: > cat tmp.mk $(info version: $(shell $(MAKE) --version)) $(info TEST: 1$\ 2) $(info TEST: [$(or \ ,$\ )]) all: @echo building $@ > make -f tmp.mk version: GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc.
