[PATCH] fix build with gcc-14 on musl

[Qian Yun]

This bug is found by gentoo ci: https://bugs.gentoo.org/937325

This happens on gcc-14 because it catches this type of error,
"-Wincompatible-pointer-types".

This doesn't happen on glibc but on musl because the type
declaration of connect/bind is a bit different.

The error message is bellow and the patch is in attachment.
