+Subject: [PATCH] Fix use of strerror_r()
+
+Don't try keep track of all platforms which follows posix standard.
+Instead, make the platform which don't follow standard to an exception
+and fall back to standard implementation for everything else.
+
+This fixes building with musl libc.
+
+Fixes #94
