There are two preferences that are rather closely related, "*-port" and 
"*-portname". The former is used with serial connections and the latter 
with TCP connections. In this latter case, the TCP port NUMBER is stored 
in *-portname (I don't know why!). [YUCK!]

The "default" target settings are supposed to be initialized by 
TargetSelection::_init_prefs, which is initialized when the target 
selection dialog is CONSTRUCTED. Sigh. That's messed up, since 
interface.tcl relies on these values in set_target_name. Yich. I'm 
surprised this worked at all.

Alas, as a quick hack, try this:

1) add a call to _init_prefs in either TargetSelection::getname or 
TargetSelection::init_target_db. I would probably do it in 
init_target_db and remove other calls to _init_pref in this file.

2) define the preference gdb/load/default-portname (set it to any 
integer) in TargetSelection::_init_prefs (follow the example for 
default-port at the end of this method).

Let me know if that fixes your problem.
