From 0f679438f36d8c2a31dfe490007e983b085caef6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20Van=C4=9Bk?= Date: Mon, 6 Mar 2023 11:19:30 +0100 Subject: [PATCH] Printf test suite fails on systems with musl libc because tests for "%m" and "%M" formats expect "Input/output error" message but musl returns "I/O error". Proposed change compares the printf output with string returned from strerror function for EIO constant.
