OK, I installed it into coreutils. Also into gnulib.
I'm CC:ing this message to bug-gnulib so here is the patch again,
relative to gnulib. The original bug report is here:
<http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html>.
This patch should fix a core dump in GNU 'sort'.
I will also fix Autoconf.

promotes to int, not unsigned int, to catch the AIX 5.3
compiler bug.
