I am not disappointed when I see a simple ./configure script that generate a clean config.mk. Would something like this be acceptable to for a suckless project ?
case "$(uname -a)" in
*Linux* )
XXXINC=/...
;;
*OpenBSD* )
XXXINC=/...
;;
*FreeBSD* )
XXXINC=/...
;;
esac
tee config.mk << EOF
XXXINC = $XXXINC
EOF
I just read this post about portability:
