Quuxplusone commented 9 years ago 
We're mostly using clang these days.

It would be nice to fix these though, because we do need to build with gcc in
certain circumstances.

cc1plus: warning: unrecognized command line option "-Wno-deprecated-register"

It looks like this one only pops up if there are other warnings in the file.
Strange.
