mmap(): MAP_ANON vs. MAP_ANONYMOUS

[Richard Hansen <rhansen%bbn.com@localhost>]

NetBSD developers,

The Austin Group (POSIX standards body) is considering standardizing
mmap() with anonymous memory:

    http://austingroupbugs.net/view.php?id=850

The current draft of the new wording (see comment #2281) uses
MAP_ANONYMOUS as the name of the mmap() flag.  NetBSD only defines
MAP_ANON, but otherwise seems conformant to the proposed wording.

Would you be opposed to defining MAP_ANONYMOUS as a synonym for
MAP_ANON?  Would you prefer POSIX to specify MAP_ANON instead?

Thanks,
Richard
