-+	* Make it possible to use --enable-timeout-stat as well as
-+	  --enable-timeout-stat=static for a static background process which
-+	  does the final stat system calls
-+	* Do not mix HAVE_TIMEOUT_STAT with WITH_TIMEOUT_STAT
-+	* Add timeout.c/timeout.h for static background process which is able
-+	  to read the file name from pipe, does the stat(2) system call, and
-+	  writes the result back to a pipe.
- 	* Really add ASCII null at command string in add_proc() of pstree.c
