No C++11/14 support even if it's explicitly specified in init.vim MacOS

[Posto578]

OS: Mac OS High Sierra
NVIM: v0.2.2
Deoplete-clang2: 787dd4d

Summarry: There is no functions suggestions from C++11 and above even if
let g:deoplete#sources#clang#std#cpp='c++14' is set.

Everything work fine from C++98.
My init.vim

Interesting fact:
Completion works with no regard for the following globals presence.

g:deoplete#sources#clang#libclang_path="/Library/Developer/CommandLineTools/usr/lib/libclang.dylib"
g:deoplete#sources#clang#clang_header ="/usr/local/Cellar/llvm/5.0.0/lib/clang"

Completion still works although I put this variables in a comment section. Weird!
