Yeah, yeah...I was thinking of a general rule (and the warning that you get
when the shared libraries are slightly out of date from SunOS 4.1.4 to 4.1.3,
for instance)...or maybe a "sometimes good" rule...or ...whatever.
We've been doing builds on SunOS 4.1.3u1, 5.3, HP-UX 9.x, IRIX 5.x, AIX 3.2.x
(from what I remember from our last major release), DEC OSF/1 3.2, and they
all basically work on later versions of their respective OS's, I think.

Agreed...a specific instance (albeit one from a company with a large market
share :-)). Of course, I have this vague recollection that at the time people
tended to try to avoid 2.x until some "it's OK" concensus was reached...that
is, the stayed with SunOS 4.x for a while.

Well...I'm not sure what the status of 10.x was for our last release, but I'd
bet that if we'd built for 10.x, we wouldn't be able to run the product on
9.x. It's a lot more practical for us to maintain one version of a product
for a given platform, if possible, if it has reasonable performance.
Vendors can maintain some for of useability/compatibility the other way
around, but with the current state of crystal ball technology it's hard for
the 9.x OS folks to support 10.x applications :-).
