+This patch add the support for --debug=c and --debug=e to make
+this option when activated will trace in stdout the activity of $(call and $(eval in the Makefile
+
+The trace use the format:
+ ### xxx -->
+ ### xxx <--
+the number of space before ### is at least 1 and increase with the nesting of eval/call
+
+usage: make --debug=c,e
