Cygwin does not implement it, probably because as
http://www.opengroup.org/onlinepubs/009695399/functions/posix_fadvise.html
says:

"The posix_fadvise() function is part of the Advisory Information option
 and need not be provided on all implementations."

Would it be possible to add some section in configure to check for existance
of posix_fadvise(), and provide a do_nothing() function if it is not
implemented?
