      # DTrace is supported on linux, solaris, mac, and bsd.  There are
      # three object files associated with DTrace support, but they're
      # not all used all the time:
      #
      #   node_dtrace.o           all configurations
      #   node_dtrace_ustack.o    not supported on mac and linux
      #   node_dtrace_provider.o  All except OS X.  "dtrace -G" is not
      #                           used on OS X.
      #
      # Note that node_dtrace_provider.cc and node_dtrace_ustack.cc do not
      # actually exist.  They're listed here to trick GYP into linking the
      # corresponding object files into the final "node" executable.  These
      # object files are generated by "dtrace -G" using custom actions
      # below, and the GYP-generated Makefiles will properly build them when
      # needed.
