1 12.2.2 How Loaded Objects Are Remade
1 ------------------------------------
1 
11 Loaded objects undergo the same re-make procedure as makefiles (⇒
 How Makefiles Are Remade Remaking Makefiles.).  If any loaded object is
1 recreated, then 'make' will start from scratch and re-read all the
1 makefiles, and reload the object files again.  It is not necessary for
1 the loaded object to do anything special to support this.
1 
1    It's up to the makefile author to provide the rules needed for
1 rebuilding the loaded object.
