--- Comment #4 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- It seems this glibc build failure disappeared between commit b880d1514c1e3dd75a6ea311a5cc956742bd713c and commit 8e836af61b7027c0819da62c12a8d18b7c46f3fc. (Not verified that the GCC change was what's relevant - my bot updated other components as well - but it looks plausible.)
