From f985113075b0c571b1b1b166fe28f87f0f291be5 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Sun, 24 Jun 2012 21:26:31 +0300 Subject: [PATCH] random_seed: Only read /dev/*random if we have unistd.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit unistd.h is used for open/read/close, but if this header does not exist, there's probably no use in trying to open /dev/*random at all.
