Jeffrey A. Law <law at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at gcc dot gnu.org --- Comment #22 from Jeffrey A. Law <law at gcc dot gnu.org> --- It's failing because sigstksz.h includes unistd.h which brings in the prototype for truncate which conflicts with the definition of truncate in the test.
