These are the responses I got from the Solaris community and SUN people:
"Yes, system 5 has always done exactly what you told it to do. The '(null)'
extension was added in BSD and picked up in Linux. To be safe use
printf("%s", variable?variable:"(null)");" - Dave Lampe
"Yes; (null) is not a valid pointer to a string so you are getting undefined
behaviour; our pilosophy is that it is best to detect such errors rather
than hide them by continuing." - Casper Dik (SUN Engineer)
So, in the future, for portability's sake, anywhere that data can be
null should be conditionalized first.
