>Description:
If / when GDB starts to support the debugging of multi-processor
(rather than multi-thread) applications the symtab code will need to
be updated a little so that several independent symbol tables are
active at a given time.

The other interesting change is a clarification of the exact meaning
of CORE_ADDR and that has had consequences for a few targets (that
were abusing that data type).
