+# INCREMENTAL_BUILD: Record the #include file dependencies.

+# NOTE: We build make include files with the suffix
+#       $(DEPEND_SUFFIX) on every compilation. These are initially 
+#       created as temp files just in case a ^C kills it in the middle.
+#	Compiler is smart enough to handle ^C and not create the .o file, or
+#	is supposed to be that smart, but the .$(DEPEND_SUFFIX) file 
+#       creation here isn't.
+#	These .$(DEPEND_SUFFIX) files are included by Library.gmk and 
+#       Program.gmk, when they exist (Search for 'make dependencies').
