<p dir="ltr">I'm figuring out why Debian xorg-server builds are failing to automatically enable kdrive's evdev input driver. It seems variable "host_os", which is referenced several times in <a href="http://configure.ac">configure.ac</a>, is undefined when Xorg is built in Debian. However, I've found no other occurrence of this variable in any other file in xserver tree.</p>
<p dir="ltr">Where host_os should be defined?</p>
