Hmm, I've never used target-specific variables in a pattern rule.
Also, since target-specific variables look like dependency specifications to
me, I put them after command-containing target rules.
So I'd write this ias
# Variable declarations
SING := Once or Twice:
# Target definitions
.PHONY: all
all: a b
a b: ; @echo $(SING)
# Dependencies
a b: SING += lala $@
which produces what you want when you enter "make" with no arguments. But I
can't really explain why! Maybe Paul can do better ...
