I'd have to add that I have a suspicion that something is still not right "library-wise"... that is, the G++ library isn't built right, or the program isn't linking right. For what it's worth - the inline __XXX functions in ctype.h do work correctly... So, I don't believe the problem isn't in the "source" per se... I'd suggest building the library with debugging enabled, linking with that and determining what is wrong. - Dave Rivers - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
