	This means that MP-RAS somehow re-acquires a controlling terminal after
forking and calling setsid() the first time.  In the Solaris case, a bug
in the pty driver caused it to happen when pushing a STREAMS module
(hence the #define name).  Linux/glibc5 has the same symptoms but it
doesn't have STREAMS so it must be acquiring it some other way (not
honouring O_NOCTTY maybe?)

	What can you tell us about MP-RAS?  Is it a SysV derivative?

	Should we just change the define to HAVE_BROKEN_O_NOCTTY.  We could
have configure do a run-tine test for it but it'd need a lot of the code
from pty_allocate().

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
