There have been some statements from MySQL in the past that implied they
might be taking a narrower view of what "distribution" meant than what
the GPL was saying. Also, it was impossible for PHP to be packaged with
MySQL libs due to incompatibilities with the GPL'd mysql connection
libs. It seems MySQL AB has clarified both on these pages:
http://www.mysql.com/company/legal/licensing/
http://www.mysql.com/company/legal/licensing/foss-exception.html
http://www.mysql.com/company/legal/licensing/faq.html
However, Fedora Core 2 still includes MySQL V 3.xx.yy because of the
issues wth V4.xx.yy's licensing. However, Suse does include the latest
version. So there's some difference of opinion on the issue from
different distros.
