I haven't looked for the LARGE_OFF_T issue, but runstatedir isn't in
vanilla autoconf 2.69, but was added sometime later.  Obviously the
configure etc. files were generated with some modified version of
autoconf 2.69.

In a similar case (libphobos), I've simply regenerated all files with
unmodifed self-built versions of autoconf 2.69 and automake 1.15.1.  I
suspect some Linux distibutions see fit to ship those
between-2.69-and-2.70 versions without any indication what they're
