+# 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').
