+	Implement the MAKE_RESTARTS variable, and disable -B if it's >0.
+	Fixes Savannah bug #7566.
+
+	* doc/make.texi (Special Variables): Document MAKE_RESTARTS.
+	* NEWS: Mention MAKE_RESTARTS.
+	* main.c (main): If we see MAKE_RESTARTS in the environment, unset
+	its export flag and obtain its value.  When we need to re-exec,
+	increment the value and add it into the environment.
+	(always_make_set): New variable.  Change the -B option to set this
+	one instead.
+	(main): When checking makefiles, only set always_make_flag if
+	always_make_set is set AND the restarts flag is 0.  When building
+	normal targets, set it IFF always_make_set is set.
