Control: reassign -2 src:autoconf
that should be fixed in the autoconf package as well.

Dear Maintainer,
See buildbot output:
Whether or not generated configure file is correct, it's inconsistent with
output generated by vanilla autoconf version 2.69 and it triggers buildbot
failures.
that is
debian/patches/avoid-undefined-behavior-for-32bit-off_t.patch:
the patch is also in Debian's autoconf (2.72) package, apparently never
forwarded.
Description: Fix undefined behavior for 32-bit off_t.
autoconf (2.69-6) unstable; urgency=low
.
* lib/autoconf/specific.m4: Use ((off_t) 1 << 31) << 31 in place of
(off_t) 1 << 62 to avoid undefined behavior when off_t is 32-bit.
Closes: #742780. Thanks to Mathieu Malaterre <[email protected]> for
reporting this bug.

Don't all Debian architectures now use 64-bit offsets (_FILE_OFFSET_BITS ==
64). In features.h,
we have:
#if defined _FILE_OFFSET_BITS && _FILE_OFFSET_BITS == 64
# define __USE_FILE_OFFSET64 1
#endif
So, maybe the above patch can now be dropped.
Some patch also adds two free() statements.
