From dc76f0c32dae689a08aa21a1d206d4cd62adb278 Mon Sep 17 00:00:00 2001
From: Marc-Antoine Perennou <Marc-Antoine@Perennou.com>
Date: Thu, 10 Oct 2013 14:26:12 +0900
Subject: [PATCH] configure: allow building with GNU Make 4
Currently, configure errors telling make 4 is too old
since it does not match our regexp.
configure.in: allow GNU Make 4.*

+On systems which do not define @code{NAME_MAX}, it may not be possible

+On some systems, @code{readdir_r} cannot read directory entries with
+very long names. If such a name is encountered, @theglibc{}
+implementation of @code{readdir_r} returns with an error code of
+@code{ENAMETOOLONG} after the final directory entry has been read. On
+other systems, @code{readdir_r} may return successfully, but the
+@code{d_name} member may not be NUL-terminated or may be truncated.
+
+@item
+POSIX-1.2008 does not guarantee that @code{readdir} is thread-safe,
+even when access to the same @var{dirstream} is serialized. But in
+current implementations (including @theglibc{}), it is safe to call
+@code{readdir} concurrently on different @var{dirstream}s, so there is
+no need to use @code{readdir_r} in most multi-threaded programs. In
+the rare case that multiple threads need to read from the same
+@var{dirstream}, it is still better to use @code{readdir} and external
+synchronization.
