17c7bba5 by Raymond Toy at 2015-04-18T16:42:53Z
Add a unix module so users can (require :unix) to get the rest of the
unix package functions.
This is for backward copmatibility.

-;;; From sys/termios.h
-
-;;; NOTE: There is both a termio (SYSV) and termios (POSIX)
-;;; structure with similar but incompatible definitions. It may be that
-;;; the non-BSD variant of termios below is really a termio but I (pw)
-;;; can't verify. The BSD variant uses the Posix termios def. Some systems
-;;; (Ultrix and OSF1) seem to support both if used independently.
-;;; The 17f version of this seems a bit confused wrt the conditionals.
-;;; Please check these defs for your system.
-
-;;; TSM: from what I can tell looking at the 17f definition, my guess is that it
-;;; was originally a termio for sunos (nonsolaris) (because it had the c-line
-;;; member for sunos only), and then was mutated into the termios definition for
-;;; later systems. The definition here is definitely not an IRIX termio because
-;;; it doesn't have c-line. In any case, the functions tcgetattr, etc.,
-;;; definitely take a termios, and termios seems to be the more standard
-;;; standard now, so my suggestion is to just go with termios and forget about
-;;; termio. Note the SVID says NCCS not NCC for the constant here, so I've
-;;; changed it (which means you need to bootstrap it to avoid a reader error).
-
-;;; On top of all that, SGI decided to change the termios structure on irix
-;;; 6.[34] (but NOT 6.2), left the old routines named the same in the library,
-;;; but introduced static functions in termios.h to redirect new calls to the
-;;; new library--which means it's important not to #include termios.h before
-;;; undefineds.h when building lisp.
