uname -m
on any DecStation 5000 yields: MIPS
on any Sun yields: sun3 sun4 sun4c, etc.
on any Apollo DN3500 yields: DN3500
on any RS/6000 yields a number which is unique to the machine
(corresponds to a chip number was the rumor)
Is there an alternate command under AIX3 which is analogous to what is normally
expected from uname -m?
Mere curiosity also prompts me to wonder why this was done in the first place?
Anyhow, the second question is regarding cpp:
Are there any predefined identifiers that (either) cpp will recognize, so that
I can #ifdef code specific to the architecture without have to cc -D<some identifier>?
I noticed that many X include files want AIXV3 defined, and imake was set up
to deal with this (although it is not predefined by either cpp).
Thanks for any help; please mail directly and I'll summarize.

I don't know, but AIX2.2.1/RT also did this and I know that the processor id number on the RT was used for software copyprotection in some commercial products.

Take a look at /etc/xlc.cfg for what is automatically defined at compile time for the different compiler invocations (xlc, cc). It seems you may want to use _AIX and _IBMR2 for AIX 3.1 specific code.
