gnome-common is legacy and now conflicts with files from autoconf-archive. Let's drop gnome-common from oe-core (maybe even meta-oe). We have three recipes in oe-core that "need" gnome-common (python3-pygobject, gnome-desktop3, matchbox-desktop). The only meaningful usage of gnome-common in their configure.ac's is GNOME_COMPILE_WARNINGS() which is already deprecated by AX_something_something() (can't remember exactly).
I think I can't get a patch in by monday, moving to M2
Initial patch sent to meta-oe, will send the oe-core set soon. http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=jku/gnome-common
oe-core patch is on the list. Once that's merged I still have to send the some fixes to meta-oe (to remove that hacks in autoconf-archive).
Removed from oe-core in 14b41d6ad6f582a229b6bd62fc4eb17f615d1ad7.
