As I just said, there is no mmap at all, period, on Berkeley VAX VM UNIX. There
are numbers reserved in the kernel's syscall table unfortunately for mmap and
friends, and I can't take them out without breaking the ABI, but this shouldn't
confuse autoconf or anything because there isn't and has never been any mmap()
in libc or any other libraries.
