Does the GNU “coreutils” compile for Interix? That will provide 'mktemp'
with '-d' feature.

The Wikipedia article for '/dev/random' also discusses '/dev/urandom'
<URL:http://en.wikipedia.org/wiki//dev/random>, and lists OSen where
it's implemented.

Generally, if it's not promised by the SUS, it would be caveat
implementeur to assume it's on any particular system.

Best IMO to use the GNU coreutils if you want their functionality.

Not without a lot of hacking.

That's what I've used until now, and it's nice. But I need something
that will work on a barebones Interix system, without coreutils.

It doesn't need to be universally portable. It just needs to work on
the platforms I'm interested in.
