frame.c: Include gansidecl.h for PROTO. 

* frame.c: Include gansidecl.h for PROTO.
        * dwarf2out.c: Move inclusion of dwarf2.h down so that PROTO is
        defined.  Don't declare dwarf2out_cfi_label here.
        * dwarf2.h: Add declarations of DWARF2 unwind info support
        functions.
        * m68k.c: Include dwarf2.h.
        (output_function_prologue): Add dwarf2 support.
        * m68k.h (INCOMING_RETURN_ADDR_RTX, DWARF_FRAME_REGNUM): New macros.
        (INCOMING_FRAME_SP_OFFSET): Likewise.
Update m68k patch from Andreas.
