Patch at http://bugzilla.kernel.org/show_bug.cgi?id=14379#c1 fixes the
warning.

Actually, the _BIF warning was fixed at commit
e899b6485c332aa2d7510739507ab5e5d7b28e59.
See http://bugzilla.kernel.org/show_bug.cgi?id=11822#c14

I made a mistake at the cleanup of predefined method table so the
warning shows up again.
