I noticed before that you mentioned you didn't want the wchar_t to be int-sized (i.e. 32 bits.) I was just wondering why. If we "shrink" the size at this point, would that have some impact on existing programs. (Currently, the typedef for `wchar_t' works down to an `int', if I'm not mistaken.) - Dave Rivers - -- rivers@dignus.com Work: (919) 676-0847 Get your mainframe programming tools at http://www.dignus.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
