The code required to support it is quite invasive to the mainline
code that is synced with upstream and is an ongoing maintenance burden.
Both the hardware and software are literal museum pieces these days and
we could not find anyone still running OpenSSH on one.
[openbsd-compat/bsd-cray.c openbsd-compat/bsd-openpty.c]
[openbsd-compat/bsd-snprintf.c openbsd-compat/fake-rfc2553.c]
[openbsd-compat/port-aix.c openbsd-compat/port-irix.c]
[openbsd-compat/rresvport.c]
These look to need string.h and/or unistd.h (based on a grep for function
names)
[sshpty.c]
for pty opening, only use the openpty() path. the other stuff only needs
to be in openssh-p; markus ok

openpty() replacement
