Since you say "by some", this makes them unreliable witnesses.

Thanks for this table. We'll be able to reference it in the future.
Consequence: If we want operating system specific predefines, we have these:
* For OpenServer 5:
#ifdef _SCO_DS
* For OpenServer 6 and UnixWare 7:
#if defined __SCO_VERSION__ || defined __sysv5__
It's clear now.
