Zack Weinberg 7e7ec48e73 Makefile.in (RTL_BASE_H, RTL_H): Correct.
* Makefile.in (RTL_BASE_H, RTL_H): Correct.
	(BUILD_RTL): Remove $(BUILD_PREFIX) from ggc-none.o.
	(genobjs): Add errors.o, ggc-none.o, and min-insn-modes.o.
	(read-rtl.o, gensupport.o, genconfig.o, genflags.o, gencodes.o)
	(genconstants.o, genemit.o, genopinit.o, genrecog.o, genextract.o)
	(genpeep.o, genattr.o, genattrtab.o, genautomata.o, genoutput.o)
	(genconditions.o): Depend on $(RTL_BASE_H) not $(RTL_H).
	(ggc-none.o, errors.o): Move rule to generators section;
	correct dependencies.
	(min-insn-modes.o): Move rule to generators section; remove
	unnecessary explicit command; correct dependencies.
	(print-rtl.o, print-rtl1.o): Correct dependencies.
	($(BUILD_PREFIX_1)errors.o. $(BUILD_PREFIX_1)ggc-none.o): Delete rule.
	(mostlyclean): Update.

	* errors.c: Include bconfig.h not config.h.  Correct comment.
	* gengtype.c, genpreds.c: Don't define NO_GENRTL_H.
	* ggc-none.c: Include bconfig.h; not config.h or tm.h.
	* print-rtl.c: Don't include tm_p.h.

	* rtl.h: Move forward-decl of struct function down where it's
	needed.  Include genrtl.h #ifndef GENERATOR_FILE, not
	#ifndef NO_GENRTL_H.  Remove unnecessary #ifdef BUFSIZ statements.
