*** Changes since GDB-4.17:
* GDB Remote protocol
For 64 bit targets, the memory packets ("M" and "m") can now contain a
full 64 bit address. The class-obscure gdb command:
set targetaddresssize 32
can be used to revert to the old behavour. For existing remote stubs
the change should not be noticed as the additional address information
will be descarded.
