From 6ca582ff96ae373e635a275626af1243a81d63a4 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 13 Jul 2011 00:30:47 +0200 Subject: libc/inet/resolv.c: comment on #endif lines While reading this file, I found it rather confusing to relate the "endif" lines to their opening counter-part. This patch adds comments to most of these lines to denote what the actually do.
