Hi
Try this to fix the dirfd thing.
I'll have to look at ssh's vsnprintf.
tmux will require a C99 compiler (or at least, some of the C99 features)
so if you want it to work on Tru64 you'll have to dig out one.
mdocml has the start of a man output mode now so when that is finished
we can use that to convert the manpage.
