ld/: * Makefile.am (AUTOMAKE_OPTIONS): Remove cygnus. Add no-texinfo.tex, no-dist, foreign. (TEXINFO_TEX): New variable. (install-data-local): Removed, not needed any more. (all): Dependencies upon info and ld.1 not needed any more. (MKDEP, DEP, DEP1, dep.sed, dep, dep-in, dep-am): Removed. (mkdep generated section): Removed. (ldgram.o, ldlex.o, deffilep.o, ldmain.o, ldfile.o): Rewrite to use automake dependency tracking mechanism. (EXTRA_ld_new_SOURCES): Add pep-dll.c, pe-dll.c, and $(ALL_EMULATIONS:.o=.c) $(ALL_64_EMULATIONS:.o=.c) so their dependencies are tracked too. (BUILT_SOURCES): New, list $(GENERATED_HFILES) to ensure they are built early. * configure.in: Use AM_MAINTAINER_MODE. * configure, Makefile.in: Regenerate.
