--- Comment #4 from Jie Zhang <jiez at gcc dot gnu.org> 2010-11-30 10:00:05 UTC --- Hah, I now know the root cause. It's "*__GI_memchr" that is added into the visible point set since it's a user provided name. But GCC looks for "__GI_memchr" later, which is not the same identifier as "*__GI_memchr". Is there a way to easily translate a "*__GI_memchr" identifier to a "__GI_memchr" one?
