Another thing you could do is: FEATURES= \ AMD \ APM \ ... WIRELESS .for feature in ${FEATURES} WITHOUT_${feature}= .endfor (that's what I did in one instance where I source the src.conf file from another Makefile). It's up to you depending on your target audience for the file on what approach you want to take. Cheers, -Garrett
