Avoid using common symbols in v850 libgloss I've had this lying around for probably a year or two at this point. It just changes all the instance of "errno" from a common symbol to an extern. I can't offhand recall where the actual definition is, but it certainly exists in the generic code. 2022-03-20 08:01:33 +08:00			`extern int errno;`
