Api error during publish to crates.io

[dtolnay]

Crates.io doesn't like our feature naming. I will look into whether this is something I can fix myself in crates.io, otherwise report an issue at https://github.com/rust-lang/crates.io.

cxx/Cargo.toml

Lines 16 to 19 in 6aa34e4

	[features]
	default = [] # c++11
	"c++14" = []
	"c++17" = []
