    !!!  if (inchannel >= 0)
        {
    #ifndef USG 
          /* On USG systems it does not work to open the pty's tty here
                   and then close and reopen it in the child.  */

What happens if you change USG to 0 in that conditional?
Does subtty get set up properly?  Does everything work after that?

USG stands for Unix Somethingorother Group.  That was the group
in AT&T that made System V.  We use it to indicate all the systems
that are derived from System V.

Also, independent of that, if you take away the #if 0 that currently
surrounds these two lines, and make them unconditional,

        if (err == -1)
          gid = - XFASTINT (p->pid);

does that fix the problem?
