You'll need to put padding on the end of the structure so that each struct will be properly aligned, but that's no big deal. Gcc will do the right thing when it sees a large const like that, and align the whole thing in .data. If you want specific aligment, you could then use gcc's __alignment__((n)) attribute. It's not portable, but the same alignment doesn't always make sense on different platforms anyways. -- Jonathan Mini <mini@freebsd.org> http://www.haikugeek.com "He who is not aware of his ignorance will be only misled by his knowledge." -- Richard Whatley To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
