Thanks for checking!

I'll update doc/posix-functions/timer_* (except timer_getoverrun)
to add Tandem/NSK and s/FreeBSD 6.0/FreeBSD 6.4/ as part of the patch.
I've also updated the "Gnulib module:" line in those docs
which I was unsure about doing.

Amended patch attached.

Well I suppose you could emulate a subset of timer_settime with setitimer,
but it would be awkward and I don't need that functionality at present.
cheers,
Pádraig.
