New Revision: 74478
URL: http://svn.boost.org/trac/boost/changeset/74478

Log:
Generate minor sdk versions backwards from current sdk version of OSX/iOS. This is the only way left to automatically do anything about registering possible versions. As Apple doesn't provide a comprehensive list of what version values are possible in a single real SDK.
