Those warnings are nothing to worry about; according to my research, the 
standard language construct we're using there had a different 
(non-standard) meaning in older g++ versions, and the warning is only 
there to alert of this potentially breaking change.

I've already prepared a change to configure.ac to set 
"-Wno-non-template-friend" when compiling with g++, but it hasn't found 
its way into the repo yet.
