local/sources/libc is libc 0.2.189 with src/unix/redox/mod.rs extended to
expose the waitid surface relibc already implements:
- idtype_t (= c_int, as relibc defines it)
- P_ALL / P_PID / P_PGID
- CLD_EXITED / KILLED / DUMPED / TRAPPED / STOPPED / CONTINUED
- extern fn waitid(idtype_t, id_t, *mut siginfo_t, c_int) -> c_int
All of it is real in relibc -- src/header/sys_wait/mod.rs defines the
types and constants, and `nm libc.a` shows `T waitid` -- but the libc
crate's Redox bindings never exposed any of it, and still do not as of
0.2.189. Any crate calling waitid therefore cannot build for
x86_64-unknown-redox:
error[E0531]: cannot find unit struct, unit variant or constant
`CLD_EXITED` in crate `libc`
which breaks nix, and through it ctrlc and rustc's bootstrap tooling --
the last thing blocking rust-native.
Values and types come from relibc, not from Linux. Every non-Redox target
is byte-for-byte upstream 0.2.189, so host builds are unaffected. Wired
into the rust workspace via [patch.crates-io]; the fork type-checks for
x86_64-unknown-redox.
Upstream-reportable: this gap belongs in the libc crate.
