You're not the first to hit this, either:

http://lists.gnu.org/archive/html/bug-gnulib/2010-10/msg00435.html

Since our party line back then was to "upgrade gcc or quit using -Werror
with old gcc", I'm marking this as a wontfix; but if you can come up
with a patch, we can reopen it.

Hi *,

building coreutils-8.12 with '--enable-gcc-warnings' fails on my SLES 10.3 server:

  CC       uinttostr.o
cc1: warnings being treated as errors
In file included from uinttostr.c:3:
anytostr.c: In function 'uinttostr':
anytostr.c:39: warning: comparison of unsigned expression < 0 is always false

gcc --version
gcc (GCC) 4.1.2 20070115 (SUSE Linux)

Have a nice day,
