The Lion libdispatch sources are now available: http://www.opensource.apple.com/release/mac-os-x-107/ http://www.opensource.apple.com/tarballs/libdispatch/libdispatch-187.5.tar.g... The configure/make buildsystem has been updated to produce a working libdispatch.dylib on Lion that can be used/installed in place of the stock version, see INSTALL for details. Next steps are to decide how to integrate the new sources into the macosforge repository; as you will discover, there has been significant refactoring/reorganization, making this not completely trivial. As a first step I was planning to import the Lion source drop on a branch, and then start reorganizing trunk similarly to make trunk changes that are missing from the branch more apparent. Before I get started on that we should make sure that all pending non-controversial patches are integrated onto trunk, does anybody have a list of what is still outstanding? (I guess this is where more consequent use of the trac ticket system on http://libdispatch.macosforge.org/trac/report would be paying off..) Daniel
