Major cutover to using system.h:

        * Makefile.in (alias.o, bitmap.o, c-aux-info.o, c-common.o,
        c-decl.o, c-iterate.o, c-lang.o, c-lex.o, c-pragma.o, c-typeck.o,
        caller-save.o, calls.o, collect2.o, combine.o, cse.o, dbxout.o,
        dwarf2out.o, dwarfout.o, emit-rtl.o, except.o, explow.o, expmed.o,
        expr.o, final.o, flow.o, function.o, getpwd.o, global.o,
        integrate.o, jump.o, local-alloc.o, loop.o, optabs.o, pexecute.o,
        prefix.o, print-rtl.o, print-tree.o, profile.o, real.o, recog.o,
        reg-stack.o, regclass.o, regmove.o, reload.o, reload1.o, reorg.o,
        rtl.o, rtlanal.o, sdbout.o, stmt.o, stor-layout.o, stupid.o,
        tlink.o, toplev.o, tree.o, unroll.o, varasm.o, xcoffout.o): Depend
        on system.h.
        * alias.c, bitmap.c, c-aux-info.c, c-common.c, c-decl.c,
        c-iterate.c, c-lang.c, c-lex.c, c-pragma.c, c-typeck.c,
        caller-save.c, calls.c, collect2.c, combine.c, cse.c, dbxout.c,
        dwarf2out.c, dwarfout.c, emit-rtl.c, except.c, explow.c, expmed.c,

        stupid.c, tlink.c, toplev.c, tree.c, unroll.c, varasm.c,
        xcoffout.c: Include system.h.  Organize include ordering so
        that stdarg/varargs comes before other system headers.  Remove
        spurious casts of functions assured of a prototype in system.h.
