 Notice the use of "+=": it is necessary for the vpath builds to work.
 
-Add wordsplit.o to the name_LIBADD or name_LDADD variable, depending on
-the nature of the object being built.
+Define the nodist_program_SOURCES variable:
 
-Modify AM_CPPFLAGS as shown in the previous section:
+  nodist_program_SOURCES = wordsplit.c
 
-  AM_CPPFLAGS = -I$(srcdir)/wordsplit
+The nodist_ prefix is necessary to prevent Make from trying to
+distribute this file from the current directory (where it doesn't
+exist of course).  It will find it using VPATH during compilation.
 
-Add both wordsplit/wordsplit.c and wordsplit/wordsplit.h to the EXTRA_DIST
-variable.
+Finally, add both wordsplit/wordsplit.c and wordsplit/wordsplit.h to
+the EXTRA_DIST variable and modify AM_CPPFLAGS as shown in the
+previous section.
 
 An example Makefile.am:
 
   program_SOURCES = main.c
+  nodist_program_SOURCES = wordsplit.c
+  VPATH += $(srcdir)/wordsplit
+  EXTRA_DIST = wordsplit/wordsplit.c wordsplit/wordsplit.h
+  AM_CPPFLAGS = -I$(srcdir)/wordsplit
+
+It is also possible to use LDADD as shown in the example below:
+
+  program_SOURCES = main.c
   LDADD = wordsplit.o
-  noinst_HEADERS = wordsplit/wordsplit.h
   VPATH += $(srcdir)/wordsplit
   EXTRA_DIST = wordsplit/wordsplit.c wordsplit/wordsplit.h
+  AM_CPPFLAGS = -I$(srcdir)/wordsplit
