At least according to Version 4.0 of Sun's _Stabs Interface Manual_,
dated February 1999, those numbers are not in use.

The _Stabs Interface Manual_ is not available on the web.  I wrote to
Sun asking why it wasn't; they told me that it was included with the
Sun toolchain, and was deliberately not available on the web.
