I was pretty sure at one time that the PPC platform had a variant of this problem, as well. If you want a definative answer, then the people to ask are the GCC implementors, who put the option into the compiler for a reason, and added the descriptive text to the .info file in the first place. Realize that this is a GCC issue, not a FreeBSD issue. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
