I just checked out http://opensource.apple.com, and was excited to see the sources for 10.7 have been released. Unfortunately, it was just a tease as the sources for libdispatch are not available yet. I know that there are folks within Apple working on merging the changes from the Apple private branch into the public MacOSforge branch, and I'm wondering how that is going. Would it be possible to get the unmodified libdispatch sources from the 10.7 build so I could try to put together a "portability patchset" that would add the Autoconf stuff and everything needed to build on other platforms? This would probably be easier and faster than having someone at Apple backport the changes from 10.7 into the MacOSforge repo. Think of it as "forward porting" the changes from MacOSforge branch instead of backporting changes the other direction. I believe this is the methodology that OpenSSH has used successfully, where the core OpenSSH team develops strictly for OpenBSD, and a separate team maintains a "portable OpenSSH" branch using a pile of patches that are applied to the upstream releases. As a suggestion, a very kind person from Apple could upload the raw 10.7 sources into the SVN tags directory at this URL: http://svn.macosforge.org/repository/libdispatch/tags/OSX_10_7 Thanks a lot! - Mark
