libass build error "implicit declaration of function 'strndup'"

Hello. Is anyone else seeing this build error from libass ? I'm a tad confused about why this error is appearing, since libass appears not to have been changed in github since 3 Jan 2026 per https://github.com/libass/libass/commits/master/ and the last time I successfully built it was 2026.02.10. Fresh Windows 11 Sandbox VM, x64 static. Build display: ``` 17:54:35 fribidi git ......................................
