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.
