+Subject: [PATCH] include unistd.h when necessary
+
+Older versions of gcc (pre-4.7) would implicitly include unistd.h in some
+of its internal headers.  With newer versions though, that is no longer
+the case, so building powertop breaks with files that use things from the
+unistd.h header but don't include it explicitly.
