--  Version used on unimplemented targets

--  Run-time symbolic traceback is currently supported on the following
--  targets:

--     HP-UX hppa and ia64
--     IRIX
--     GNU/Linux x86, x86_64, ia64
--     AIX
--     Solaris sparc and x86
--     Tru64
--     OpenVMS/Alpha
--     Windows NT/XP/Vista

--  This version is used on all other targets, it generates a warning at
--  compile time if it is with'ed, and the bodies generate messages saying
--  that the functions are not implemented.
