I booted ubuntu 16 and it has gcc 5.4. This patch worked just fine.
Please let me know if check_cxx11_for_libdpx.diff is no longer needed ??? and if I should check in the above.
I checked new patch (from my memory) on Slackware and it worked. So yeah, I think this check in configure.ac is not needed anymore.
Thank you -- I will check in the patch for cinelerra/Makefile soon. So this means that the following additional line in " check_cxx11_for_libdpx.diff" as shown below is not needed either? It does not seem to match anything else and I have not tested it.
