I suppose it is the label returned by "uname -m" on FreeBSD or which 
ever Unix.

This is what I was wondering. If it existed I would use it.

Does in my code. I am porting the FreeBSD sysctl call :-)

If you look in the sys/sysctl.h file you will see a few externs. The 
FreeBSD kernel file kern/kern_mib.c references these variables as they 
are exported via the sysctl call. If there was something around I would 
define them and have provide sysctl provide them.

Sure, and it appears in a header file that included. Is this a problem ?

You may remotely via a protocol such as SNMP.

It was a case of looking at what it takes to include these variables. If 
it is not worth including that is fine.
