I support Ralf and oppose any change.

I checked the FreeBSD man page and the malloc code. FreeBSD allows malloc to be
configured via /etc/malloc.conf at the system level and also via the
environment using MALLOC_OPTIONS. The 'V' option causes malloc to return a NULL
pointer rather than the default behaviour of allocating a 1 byte. Any code in
FreeBSD that cannot handle both cases is broken. Also the C FAQ covers the
topic with http://c-faq.com/ansi/malloc0.html. I agree with the comment in the
FAQ.
