I hacked on and simplified it by removing a lot of sexy features he
|
|
|
|
|
had added, and some of the (unix specific) workarounds he'd done
|
|
|
|
|
for other GDB problems - which if they still exist should be fixed
|
|
|
|
|
in GDB, not in a remote-foo thing . I also made it conform more to
|
|
|
|
|
the doc I have; which may be wrong.
