The information above doesn't seem very consistent with the present situation: unstable has gcc-5 >= 5.2.1-13 since 2015-07-30. Ever since, there wasn't actually a newer version uploaded to experimental. Now looking at ppl, it has been uploaded with arch:all packages only on 2015-08-26, and looking at, e.g., the amd64 build log the "Toolchain package versions" does confirm: g++-5_5.2.1-15 Hence I'm not quite sure what might be going on here?! Thanks a lot, Michael
