The price for the fastest reply goes to Art Freeman who gave the right
answer just 20 minutes after I sent my mail:

One can distinguish 4.1.3_U1 and 4.1.3_U1_B with the command


If it's release "B" then you will see "* Release: 4.1.3_U1 Version B"
otherwise it's release "A".

Now if only sun could supply this info on their web pages. They suggest
using `uname' which displays 4.1.3_U1 for both releases.

This is a wonderful list,
