+Subject: [PATCH 1/4] use POSIX poll.h instead of sys/poll.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+POSIX specifies that <poll.h> is the correct header to
+include for poll()
+  http://pubs.opengroup.org/onlinepubs/009695399/functions/poll.html
+whereas <sys/poll.h> is only needed for ancient glibc (<2.3),
+so let's follow POSIX instead.
+
+As a side-effect, this silences a warning when compiling
+against the musl C-library:
+
+In file included from ./boost/asio/detail/socket_types.hpp:61:0,
+                 from ./boost/asio/ip/address_v4.hpp:21,
+                 from ./boost/asio/ip/address.hpp:21,
+                 from libs/log/src/init_from_settings.cpp:65:
+<sysroot>/usr/include/sys/poll.h:1:2: warning: #warning redirecting incorrect #include <sys/poll.h> to <poll.h> [-Wcpp]
+ #warning redirecting incorrect #include <sys/poll.h> to <poll.h>
+  ^~~~~~~
+
+etc.
