mrs at gcc dot gnu.org <mrs at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mrs at gcc dot gnu.org --- Comment #15 from mrs at gcc dot gnu.org <mrs at gcc dot gnu.org> --- The fix requires that binutils also support the () spelling as the test runs on all x86 systems. Also, it will break systems older then when () was first introduced, if it was after filds itself was supported. I don't know when each was new.
