A little bit of an odd statement, but understandable from a
VMS enthusiast :-) Unix is a collection of operating systems, so
providing a binding to Unix is not a very well defined concept.

Certainly all Ada compilers come with various ways of
interfacing to operating systems functions.

Many functions can be done using the portable POSIX interface.
This is desirable where possible, since it avoids the nasty
trap that particularly VMS programmers get stuck in of doing
everything with Starlet and building completely non-portable
programs. Many of these Starlet functions could perfectly
well be performed using a good posix interface.

Other bindings to well established interface sets are also
generally available, and these are largely portable. In addition
every compiler comes with various operating system interfaces
that are not necessarily portable to other Ada compilers.
