Works with >=gcc-4.9 or clang.
Indeed, I missed this Changelog note from a 3.13.0 RC: * Code cleanup and modernization, building FileZilla now requires a C++14 compiler Thanks for the report, I'll add a test like we have in llvm (and yes that will mean at least gcc 4.9 or a recent clang)
I added the check, emerge will only go on if compiler accepts -std=c++14 flag
