 This is a lightly hacked version of the ruptime from
	sunsite.unc.edu:pub/Linux/system/network/sunacm/Other/ruptime
It appears to yield the correct results on Linux systems, and that's
all the author really cares about at the moment (other systems supply
their own ruptimes and so don't need them supplied).

 It relies on the rwhod from rwho-0.10 RPM from RedHat, in this case for
RedHat 5.1. It has its own private copy of the rwhod.h from that source
package (evil me).

BUGS: this should be part of rwho.
