Hi, I just realized the last part might be confusing.
What I meant by "looks identical" is only the output of the *second* grep (see linked script), not the whole file:
BUILT_SOURCES = x.c all: $(BUILT_SOURCES) distdir: $(BUILT_SOURCES) check: $(BUILT_SOURCES) install: $(BUILT_SOURCES) install-exec: $(BUILT_SOURCES) -$(am__rm_f) $(BUILT_SOURCES) Have fun, JensG
