Thanks. OpenBSD doesn't have --defined-only. I believe the following
change will work for *BSD:

     | awk '{
               if ($2 != "U") if ($3 ~ /^_ZTV/ || $3 ~ /^gHotSpotVM/) print "\t" $3 ";"

So the whole chunk looks like this:

OS_NAME=`uname -s`
BSD_OS=${OS_NAME##${OS_NAME%BSD}}

if [ "$BSD_OS" == "BSD" ] ; then
$NM $* \
    | awk '{
              if ($2 != "U") if ($3 ~ /^_ZTV/ || $3 ~ /^gHotSpotVM/) print "\t" $3 ";"
              if ($2 != "U") if ($3 ~ /^UseSharedSpaces$/) print "\t" $3 ";"
              if ($2 != "U") if ($3 ~ /^_ZN9Arguments17SharedArchivePathE$/) print "\t" $3 ";"
          }' \
    | sort -u
else
$NM -Uj $* | awk '
