- Subject: [RFA] windows-nat.c: Enable processed input at startup
This is the patch I was talking about in
a reply to this thread:
http://sourceware.org/ml/gdb/2010-04/msg00113.html
It ensures that at startup, if GDB can connect to the console
the console mode is modified to enable processed input.
This make '^C' (ascii #3) to be interpreted as a
control event.

* windows-nat.c (_initialize_windows_nat): Try to set
ENABLE_PROCESSED_INPUT for console mode if accessible.
