In Makefile.am

 # Make sure needed headers are built before trying to compile these files
 # (Assume ddd.C is the first source file to be built.)

This is not a good assumption when people use make -j$(nproc). Please either:

fully list headers, as such:

-resources.o: Ddd.ad.h
-show.o: build.h
+resources.o: Ddd.ad.h version.h
+show.o: build.h host.h version.h


or else, use BUILT_SOURCES to indicate files that should be built early.
