On HPUX it seems to be spelled MAP_ANONYMOUS. At least if this means
the same thing as what you are talking about. The HP man page says
: The MAP_FILE and MAP_ANONYMOUS flags control whether the region to be
: mapped is a mapped file region or an anonymous shared memory region.
: Exactly one of these flags must be selected.
