I'm running the stable branch of Gentoo on our server, and it's using gcc-3.3.5. On our desktops, I run the unstable branch of Gentoo, and they're using gcc-3.4.3. Unless there are some *major* issues in previous versions of gcc, I would choose one of them over 4.0 at the moment. 4.0 is an initial release, and a major rewrite. Many bugs will have been introduced during the rewrite. As for performance, I've read a number of forum posts saying that 4.0 is currently no better ( on average ... better in some cases, worse in others ) than 3.4.3. This will improve with further releases - there is apparently a lot of potential - but for now I would only use 4.0 on development machines. In fact, if you are interested in getting MySQL compiled with gcc-4.0, perhaps you should do a Gentoo install using gcc-4.0 and pave the way for the rest of us :) -- Daniel Kasak IT Developer NUS Consulting Group Level 5, 77 Pacific Highway North Sydney, NSW, Australia 2060 T: (+61) 2 9922-7676 / F: (+61) 2 9922 7989 email: [EMAIL PROTECTED] website: http://www.nusconsulting.com.au -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
