Doesn't build: no intern in parse::token

Trying to build using rustc 1.16.0-nightly (47c8d9fdc 2017-01-08), but it fails:

error[E0432]: unresolved import syntax::parse::token::intern
--> /Users/joel/src/postgres-extension.rs/macros/src/lib.rs:11:5
|
11 | use syntax::parse::token::intern;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no intern in parse::token

error[E0432]: unresolved import syntax::parse::token::InternedString
--> /Users/joel/src/postgres-extension.rs/macros/src/lib.rs:21:5

21 | use syntax::parse::token::InternedString;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no InternedString in parse::token

error: aborting due to 2 previous errors

error: Could not compile postgres_extension_macros.
