The problem is not the call.  Such a call exists, since Vista even
one with very simple usage.  The problem is that this call has
been created for SUA, and some Win32 libs as well as the console
subsystem don't work with this call because there never have been
made provisions for a fork call in the Win32 libs.  Chances for
a change are rather low.
