Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- There could be other reasons. Anyways this is not something configure should say. Also "error: cannot run C compiled programs." comes from autoconfig and not GCC's configure.ac :). Maybe file a bug there .
