 **Root cause**: `wchar.h` included `<stdio.h>` before defining `wint_t`/`mbstate_t`, and
 `inttypes.h` included `<wchar.h>` instead of `<stdint.h>`+`<stddef.h>` per POSIX spec.
 
-**Fix** (commits `d28963d`, `a2e4cd2` in `local/sources/relibc/`):
+**Fix** (commits `d28963d`, `a2e4cd2`, `826a984f`, `4eabdf20` in `local/sources/relibc/`):
 1. `wchar/cbindgen.toml`: Types defined in `after_includes` before `#include <stdio.h>`
 2. `inttypes/cbindgen.toml`: `sys_includes = ["stdint.h", "stddef.h"]` (POSIX compliant)
+3. **stddef → cbindgen** (`826a984f`, integrates upstream `3be84f4b`):
+   - Eliminated hand-written `include/stddef.h` (was missing `wchar_t`)
+   - `stddef.h` now generated by cbindgen from `src/header/stddef/cbindgen.toml`
+   - Split into modular `bits_*` sub-headers (each can be included independently):
+     - `bits/wchar-t.h` — `wchar_t` with `_WCHAR_T` guard + `__WCHAR_TYPE__`
+     - `bits/size-t.h` — `size_t` from Rust `usize` via cbindgen `[export]`
+     - `bits/null.h` — `NULL`: `nullptr` (C++11), `0L` (C++), `(void *)0` (C)
+4. **wchar.h include ordering** (`4eabdf20`):
+   - `wint_t` defined BEFORE `#include <stddef.h>` (avoid GCC `__need_wint_t` conflict)
+   - Removed redundant `wchar_t` redefinition (now provided by `bits/wchar-t.h`)
+5. **stdbool.h POSIX fix** (`4eabdf20`): `#define bool _Bool` replaces non-standard `typedef _Bool bool`
