You probably didn't rebuild the entire compiler, did you? If no, there are very likely missing dependencies in the Fortran Makefile fragment, namely: fortran/f95-lang.o: $(GFORTRAN_TRANS_DEPS) fortran/mathbuiltins.def \ gt-fortran-f95-lang.h gtype-fortran.h $(CGRAPH_H) $(TARGET_H) fortran/cpp.h \ $(BUILTINS_DEF) fortran/types.def \ libfuncs.h expr.h
