Saying something along the lines of ...
PAREN :=(
LIST :=a b c
LISTP := $(addprefix $(PAREN), $(LIST))
all:
echo "$(LISTP)"
... is probably what you want.
1. Most special characters in GNU Make have to be parametrized and
often times $(subst)'ed in place of existing variables.
2. Not inserting quotes around the echo string will result in shell
syntax failures because `(' is a delimiter in bourne shell.
