In the case the system does not have /dev/ptmx and has an openpty function,
the safest approach is to use that functions - we don't know which device
files it may try.
But this works only if HAVE_OPENPTY is defined, and - you're right - the
problem is that it does not get defined.
This should fix it:

* m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when openpty exists.
