The test-float test is failing on ppc64 with:
gcc version 4.4.4 20100630 (Red Hat 4.4.4-10) (GCC)
(albeit an aging Fedora 12 system)
due to the failure of this assertion:
ASSERT (LDBL_MIN_EXP <= DBL_MIN_EXP);
It fails because of these numbers:
$ :|gcc -dD -E -include stddef.h -|grep -E 'L?DBL_MIN_EXP'
#define __DBL_MIN_EXP__ (-1021)
#define __LDBL_MIN_EXP__ (-968)
I propose to comment out that test for now, just prior
to the coreutils-8.13 pre-release snapshot.
I'll wait an hour in case someone objects.

I need to get in the habit of running gnulib's "make check".
Both of these would have been caught.
