--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- This does not make sense: > When GCC was built w/ fixincludes enabled, an old fixincluded'd version of > the headers is used which has the old time64 macro, and therefore > __pthread_cond_timedwait64 isn't being made available. If you install a new version of glibc, you need to rerun fixincludes (which does get installed these days and had for a long time now).
