Solaris version number stew

[david at thekramers.net (David Kramer)]

My next project at work will be porting our application from Solaris 7 to
Solaris 8.  Mind you, I'm not a Sun expert, and have not tried it yet
(hardware is on order).

I'm looking for information on the difference between the two from a C/C++
software developer's perspective.  And, of course, the differences between
our existing compiler (Visual C++ 2.4) and whatever version comes with
Solaris 8 (or is the newest stable version).

Any information would be greatly appreciated, but links to documentation
is just as welcome.  I'm not afraid of work, I just didn't have much luck
scouring Sun's website for porting documentation.

Another question, which should be a lot easier to answer: I'm getting very
confused by the multiple version numbers for the same release of
Solaris/SunOS.  It's really impeding my ability to do research.

My understanding is that
2.6   =   2.6
5.7   =   Solaris 7, but some people call it 2.7
5.8   =   Solaris 8, but some people call it 2.8
But I have seen references to a 4.x series too.  Can someone point me
towards a Rosetta Stone or babelfish?  Also, what version of the  C++
compiler comes with each of these?  I think we are currently using visual
C++ 4.2.

P.S.- I thought there would have been more Sun/Solaris newsgroups, but I
only found a few global ones.

TIA.
