Subject: eclass/ros-catkin.eclass: Build all ROS packages in C++11 mode.
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=c0e7c659072809089e00cf1ce582cea58158dcb2;p=gentoo.git

eclass/ros-catkin.eclass: Build all ROS packages in C++11 mode.

Some of them require it, all dev-ros category should have been fixed to build in C++11 mode now.
Suggested by Victor Mataré in bug #605466, fixing all its dupes too.
