I'm not sure. It should be easy to translate the flags,
see the appended patch. (just compile-tested, I'm
illiterate in C#)
Otoh, I'm not sure whether it is a good idea to expose
such a platform dependant function to an abstract
environment. (It certainly does not belong into a
"Posix" namespace.) This will only lead to unportable
C## programs. But this was the decision of the mono
authors.

As said, programs expecting Linux semantics, and
not setting MAYMOVE could assume that the address
doesn't change.

In that case it is a wrapper for C# programs running
in the mono VM. The programs using that call are yet
to be written (well, I hope not...).
