Why is it valid for there to be a previous forward declaration? I don't think
it's permitted for applications to make their own declarations of these types.

--- Comment #7 from Florian Weimer <fw at deneb dot enyo.de> ---
Fixed for 2.40 via:
commit 8d7b6b4cb27d4dec1dd5f7960298c1699275f962
Author: Florian Weimer <fweimer@redhat.com>
Date: Sat May 18 09:33:19 2024 +0200
socket: Use may_alias on sockaddr structs (bug 19622)
This supports common coding patterns. The GCC C front end before
version 7 rejects the may_alias attribute on a struct definition
if it was not present in a previous forward declaration, so this
attribute can only be conditionally applied.
This implements the spirit of the change in Austin Group issue 1641.
