Description Craig Keogh 2009-08-21 20:43:52 UTC

Building dbus master using jhbuild (with gnome-external-deps-devel) on Ubuntu Karmic. I believe Ubuntu, Gentoo and possibly others have some extra settings to gcc to check return values. Error below:

git pull --rebase
Current branch master is up to date.
