Sun-3 vs. Sun-4 run-time library differences?

[Frank Malczewski]

I was wondering whether there might be differences between the run-time
librares distributed with the Sun-3 and Sun-4 workstations (e.g.,
different parameter requirements, different numbers of parameters, etc).

Similarly, might there be any other differences of which one need be aware?

(I'm pretty new to the unix realm, so any help/pointers would be appreciated.)
