Current versions of top (3.5beta<mumble>) will actually work regardless
of OS release version.

Since there's usually only a handful of executables that requires
an OS specific version, you'd typically write a wrapper script:

#!/bin/sh

osrev=`uname -r`
if [ -x "$0.$osrev" ]
then
    exec "`basename $0`.$osrev" "$@"
    exec "$0.$osrev" "$@"
else
    echo "$0: not found" 1>&2
    exit 1
fi

Urban legends have it that you'd also need to take the architecture
(sun4u/sun4m/sun4d) into account but that has never been true on
Solaris 2.x.

With the advent of 64 bit Solaris the picture is somewhat muddier:

 find . -name top\*
 ./top (wrapper script)
 ./top.5.3
 ./top.5.4
 ./top.5.5
 ./top.5.5.1
 ./sparcv7/top.5.7
 ./sparcv7/top.5.8
 ./sparcv7/top.5.9
 ./sparcv9/top.5.7
 ./sparcv9/top.5.8
 ./sparcv9/top.5.9
 ./top.5.7 (copy of isaexec)
 ./top.5.8 (copy of isaexec)
 ./top.5.9 (copy of isaexec)

As early as 5.5.1 I had a version of top that ignored /dev/kmem open
failures and still runs on Solaris 9 (32 bit binary on 64 bit OS)
