HP-UX doesn't have MAP_ANON but it does have MAP_ANONYMOUS. Moreoever,
according to mmap(2) on RHEL:
       MAP_ANONYMOUS
              The mapping is not backed by any file; the fd and offset argu-
              ments are ignored.  This flag in conjunction with MAP_SHARED is
              implemented since Linux 2.4.

       MAP_ANON
              Alias for MAP_ANONYMOUS. Deprecated.
