yeah, C++ fixed this historical wart of C. sorry for not clarifying. iiuc (and i could be wrong as i'm not old enough to have lived through it), this dates back to when C (ANSI?) didn't have prototypes. with a lot of code out there relying on the behavior, gcc never stopped accepting it. i wonder if we could argue for like a newer GNU standard to reject it. -mike
