Not unless it’s operating in a mode I’m not specifying…

all:
	PATH=${PATH}:A
	echo path is: ${PATH}
	echo path is: $$PATH

echo path is: /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/home/ngie/bin
path is: /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/home/ngie/bin
echo path is: $PATH
path is: /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/home/ngie/bin
