No it doesn't. If it did, it idiomatic rules such as

binary: $(OBJS)
	$(CC) -o $< $(OBJS)

would not work.


It is even easy to check this:

pc-043:~/foo$ cat Makefile
foo = a b
bar:
        ./echonum $(foo) stop
pc-043:~/foo$ cat echonum
#! /bin/sh
while true ; do
  echo $1
  [ "$1" = stop ] && exit 0 ;
  shift
done
pc-043:~/foo$ gmake bar
./echonum a b stop
a
b
stop
pc-043:~/foo$ gmake --version
