Indeed. Atom keeps thinking .C is an actual „ANSI C“ thing. If I were to make a suggestion to the GCC dev’s, then I probably could also swiftly word it as:

$ find gcc-src -name "*.C“ | while read f; do mv $f $(echo $f | sed 's/\.C/\.cxx/g’); done

In other words; .cxx, .cpp or .cc seems like a solution that works across platforms. Since .cc is already used at some places, I would recommend that this is to be the extension to choose.

One does not neccessarily need to make a dev apply hacks all over just to start development.
