+Subject: [PATCH] Fix freebsd build.
+
+It turns out system headers included by generated plugin.pb.h file already contains
+major/minor macro definitions when built on FreeBSD and we need to add #undefs to
+the generated header file.
+
+This change also fixes another compile error regarding EXPECT_DEATH on FreeBSD.
