Subject:         * headers.txt (gnu/gcj/jvmti/Breakpoint.h)[DIRECT_THREADED]: 
        Add _Jv_RewriteBreakpointInsn friend declaration.         *
 gnu/gcj/jvmti/natBreakpoint.cc (_Jv_RewriteBreakpointInsn)        
 [DIRECT_THREADED]: New function.         * gnu/gcj/jvmti/Breakpoint.h:
 Regenerate.         * interpret-run.cc: Define new REWRITE_INSN macro.       
  Changed all occurrences of insn rewriting to call REWRITE_INSN.
