From 26e7005728f0eea2972474e6be2905c467661237 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Sat, 18 May 2024 09:33:19 +0200 Subject: 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.
