Subject: [PATCH] Add missing includes to zed_log.c
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8

GCC 4.9.4 complains about implicit function declarations when building
against musl on Gentoo.

zed_log.c: In function ‘zed_log_pipe_open’:
zed_log.c:69:7: warning: implicit declaration of function ‘getpid’
       (int)getpid());
       ^
zed_log.c:71:2: warning: implicit declaration of function ‘pipe’
  if (pipe(_ctx.pipe_fd) < 0)
  ^
zed_log.c: In function ‘zed_log_pipe_close_reads’:
zed_log.c:90:2: warning: implicit declaration of function ‘close’
  if (close(_ctx.pipe_fd[0]) < 0)
  ^
zed_log.c: In function ‘zed_log_pipe_wait’:
zed_log.c:141:3: warning: implicit declaration of function ‘read’
   n = read(_ctx.pipe_fd[0], &c, sizeof (c));

The [-Wimplicit-function-declaration] at the end of each warning has
been removed to meet comment style requirements.

The man pages say to include <sys/types.h> and <unistd.h>. Doing that
silences the warnings.
