From c3f476a763412be51b4df0e748af04d4150a2c71 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fping: Initialize msghdr struct in a portable way
Initializing the structure assuming glibc layout results in
compile errors on musl, therefore do partial intialization and then
assigning the members individually.
