Hi,

I'm guessing this means I need to enable C++11 within jhbuild.  Do I do 
this in my .jhbuildrc or should this be a compiler flag added within the 
glibmm configure.ac?

This seems to be a -Wc++0x-compat warning. Do you have that in your
jhbuild config file somehow?

Or maybe you just need to run autogen.sh again.
