+Subject: [PATCH] scanner: Add configure check for strndup
+
+Some platforms may not have strndup() (e.g. MinGW), so provide a
+equivalent implementation if it's not found.

+Subject: [PATCH] Move wl_priv_signal to wayland-server-private.h
+
+Including wayland-server-core.h in wayland-private.h is problematic
+because wayland-private.h is included by wayland-scanner which should be
+able to build against non-POSIX platforms (e.g. MinGW). The only reason
+that wayland-server-core.h was included in wayland-private.h was for the
+wl_private_signal definitions, so move those to a
+wayland-server-private.h file that can be included by both
+wayland-server.c and the tests.
