Unfortunately, that is a Linux feature. E.g. FreeBSD 4 has a
sys/cdefs.h, but does not define anything relevant.

A check for 2.96 has been committed a while ago. What do you
think about adding the malloc attribute to functions which
either return NULL or an emalloc'ed pointer?
I've also added a few other attributes in a couple of places.
What do you think about the nonnull attribute?
