As it's long double it's probably a matter of differences between x86_64 
implementations; in such cases the ulps file should generally just be 
updated by the person seeing the failures following the instructions at 
<http://sourceware.org/glibc/wiki/Regeneration>.

It is not clear to me if that would not break other x86_64 implementations.

test-ildoubl still fails with the error above even with the regenerated
sysdeps/x86_64/fpu/libm-test-ulps:

make[2]: *** [/var/tmp/glibc-build/math/test-ildoubl.out] Error 1

test-ldouble is fine now.

Could you give me a real name, so that I can properly name you in the
ChangeLog?

The patch is fine, it's just a 1 ulp difference..
