Hi Ralph,

Thanks for the reply. Haven't built much with Linux, but digging a
bit, that's what I found. Actually using FreeBSD 12 for development,
but needed to make sure it would build and run on Linux as well. Just
included <linux/time.h>, which fixed it.

Devuan looks really good and have run Debian in the past, so will be
looking more into it, xfce4 and systemd free...

Chris
