Installing S on an RS/6000 running AIX

[Paul M Wright]

I am attempting to install S onto an rs/6000 running AIX.
I am using an '89 version of S, which does not recognize
this as an alternative for its menu-driven installation;
thus, I need to create my own $I/u/mach.h and $I/cdefs.h.
Can anybody tell me what I need to include in these files,
or better yet, does someone have have a working copy of these
files that I could port to my machine?

Thanks in advance,

P.M.Wright
