Summary:                    ptsname() does not work in the no-TIOCGPTN case
Description: 
When no TIOCGPTN definition is present in the kernel headers, the library's
ptsname() function will not work.

The libc/stdlib/ptsname_r.c file is the problem.  This file includes a
complicated nest of #if directives.  One of these #if's has the opposite
sense from what is required.

Simply removing one character allows PTY-using programs such as "script"
to work.  I've done that in the attached patch.

Note: to get the PTY-related functions working fully on an old kernel, it
is also necessary to supply a /sbin/pt_chown program.
