I compiled sane from git as mentioned below. Can I ignore the messages with autoreconf?
$ cd /install/linuxins/sane-git/src/ $ git clone git://git.debian.org/sane/sane-backends.git $ cd /install/linuxins/sane-git/src/sane-backends/ $ autoconf aclocal.m4:17: warning: this file was generated for autoconf 2.69.
