  26 /* The numbering of these signals is chosen to match traditional unix
  27    signals (insofar as various unices use the same numbers, anyway).
  28    It is also the numbering of the GDB remote protocol.  Other remote
  29    protocols, if they use a different numbering, should make sure to
  30    translate appropriately.
  31
  32    Since these numbers have actually made it out into other software
  33    (stubs, etc.), you mustn't disturb the assigned numbering.  If you
  34    need to add new signals here, add them to the end of the explicitly
  35    numbered signals, at the comment marker.  Add them unconditionally,
  36    not within any #if or #ifdef.
  37
  38    This is based strongly on Unix/POSIX signals for several reasons:
  39    (1) This set of signals represents a widely-accepted attempt to
  40    represent events of this sort in a portable fashion, (2) we want a
  41    signal to make it from wait to child_wait to the user intact, (3) many
  42    remote protocols use a similar encoding.  However, it is
  43    recognized that this set of signals has limitations (such as not
  44    distinguishing between various kinds of SIGSEGV, or not
  45    distinguishing hitting a breakpoint from finishing a single step).
  46    So in the future we may get around this either by adding additional
  47    signals for breakpoint, single-step, etc., or by adding signal
  48    codes; the latter seems more in the spirit of what BSD, System V,
  49    etc. are doing to address these issues.  */
