Warning fixes:

        * Makefile.in (decl2.o): Depend on dwarf2out.h and dwarfout.h.
        * cp-tree.h: Add prototype for `maybe_print_template_context' and
        `maybe_make_one_only'.
        * decl.c (auto_function): Remove unused variable `decl'.
        * decl2.c: Include dwarf2out.h and dwarfout.h.
        * lex.c: Remove redundant declarations of `set_float_handler' and
        `asm_out_file'.
