Description
Currently, core::ffi::c_char on AIX is i8, but AFAIK, the default of this platform is unsigned (u8).
Defaults
-qchars=unsigned

$ clang --version

#define __CHAR_UNSIGNED__ 1Rust:
$ tail -2 src/lib.rs
const C: core::ffi::c_char = 0u8;
$ cargo check -Zbuild-std=core --target powerpc64-ibm-aix
