commit c3dcab92ff903422814573d6315ed2a1417080f6
Author: Andrew Savchenko <bircoph@gentoo.org>
Date:   Mon Aug 1 12:03:51 2022 +0300

    Include <sys/select.h> for fd_set
    
    When fd_set is used <sys/select.h> should be included.
    On glibc it is done implicitly via other headers,
    on musl it must be explicitly provided.
