interix 3.5 select bug

[Markus Duft]

Hi!

I have a more or less trivial patch for the nanosleep replacement for
interix. The problem I ran into is, that select() has a bug, making it fail
with "bad address" if the number of fd's to select on is zero. Setting the
set-size to 1 solves the problem, and should not damage anything else around
there, since all the sets are NULL anyway.

The patch can be found here:

utils-6.12-interix-sleep.patch

If you need more info, please contact me.

Cheers, Markus Duft
