Message:

A long time ago (2001), some PPC Linux distribution's C libraries
didn't define madvise(). It's probably time to stop doing it for
them.

(A bug that affected the LinuxPPC64 port went away after this change,
but it's not clear why; then again, that may have to do with the
PowerOpen calling sequence and the TOC.)

If anyone's still running YDL 2.0 ... upgrade.
