How to detect Classic?

[Thomas J McGrath III]

Since OS9 is no longer supported in Panther, The way "Classic" is 
handled is completely different in 10.2.3 +.
I ran into this and had a couple of workarounds for the path.
It would be nice to have a simple way of finding the true platform and 
environment we are running in.
