        * except.h (output_function_exception_table): Adjust prototype.

        * final.c (final_scan_insn_1) <NOTE_INSN_SWITCH_TEXT_SECTIONS>: Output
        the first part of the exception table and emit unwind directives.
        * config/i386/i386-protos.h (i386_pe_end_cold_function): Declare.
        (i386_pe_seh_cold_init): Likewise.
        * config/i386/cygming.h (ASM_DECLARE_COLD_FUNCTION_NAME): New macro.
        (ASM_DECLARE_COLD_FUNCTION_SIZE): Likewise.
        * config/i386/i386.c (x86_expand_epilogue): Fix wording in comment.

        * config/i386/winnt.c: Include except.h.
        (struct seh_frame_state): Add reg_offset, after_prologue and
        in_cold_section fields.
        (i386_pe_seh_end_prologue): Set seh->after_prologue.
        (i386_pe_seh_cold_init): New function.
        (i386_pe_seh_fini): Add COLD parameter and bail out if it is not equal
        to seh->in_cold_section.
        (seh_emit_push): Record the offset of the push.
        (seh_emit_save): Record the offet of the save.
        (i386_pe_seh_unwind_emit): Deal with NOTE_INSN_SWITCH_TEXT_SECTIONS.
