Description

Code

Many crates that use bindgen are now failing. For example:

https://github.com/asomers/gstat-rs/blob/master/freebsd-libgeom-sys/build.rs
https://github.com/asomers/mdconfig/blob/master/bindgen/bindgen.sh
https://github.com/asomers/capsicum-net/blob/master/bindgen/bindgen.sh

The bindgen output looks like normal, except that it also has several rewriting static lines mixed in. For example:

#![allow(non_camel_case_types)] use casper_sys::cap_channel_t; use libc::sockaddr; /* automatically generated by rust-bindgen 0.69.4 */

rewriting static rewriting static pub const CAPNET_CONNECT: u32 = 16; pub const CAPNET_BIND: u32 = 32; pub type __uint8_t = ::std::os::raw::c_uchar; pub type __uint32_t = ::std::os::raw::c_uint;
