Curiously, the behavior is different on different platforms/versions
of GDB.

Hm, you are right. Lewin, you can make sure by enabling remotedebug in
GDB - that will show you if the incoming data is in raw or O-packet
format.

I'm not sure why it shouldn't be in O-packet format, unless you are
writing to a raw device (fprintf? - do we actually have that?)
