There has been a change in the XFS header files, where there's a
problem:
(from config.log)
configure:23389: gcc -c -g -O2 conftest.c >&5
In file included from /usr/include/xfs/xfs.h:37:0,
from conftest.c:86:

off64_t isn't there by default.
Kernel/Headers: uname -a

My research turned up:
http://oss.sgi.com/archives/xfs/2016-01/msg00385.html
Ironically:
http://oss.sgi.com/archives/xfs/2009-11/msg00151.html
So it is known there was issues with off64_t in the past.
A google search showed other projects having issues, alas. What is a
good next step? I'd be glad to provide a revert patch for the kernel.
Cheers,
