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