We think we followed all your requests/advice/suggestions (thanks!). We were unable to compile the current master (!) on Ubuntu and MacOS unless we added -std=c++11 to the Makefile(s) compiler flags. Note that this is NOT related to this pull request / the ECO Force. With this compiler flag, the current master works well with the fix_orient_eco (now renamed). The fix has been moved to USER-MISC (but we hope to get it to MISC later). We can't "make style_check ", but we have added our command to commands_fix.rst. We don't know GitHub well enough, so we don't know how to make sure that the PR #2122 was already included in the master, which we downloaded today.
