[RFC] win32-nat.c 'set new-console' and interruption

This is what I get with my patch:

(top-gdb) set new-c
(top-gdb) r ./gdb
Starting program: /usr/local/src/gdbcvs/build-bare/gdb/gdb.exe ./gdb
[New Thread 480.0x2ec]
[New Thread 480.0xc60]
[New Thread 480.0xae4]
[New Thread 480.0xe7c]

Program received signal SIGINT, Interrupt.
[Switching to Thread 480.0xe7c]
0x7c901231 in ntdll!DbgUiConnectToDbg ()
   from /cygdrive/d/WINDOWS/system32/ntdll.dll
(top-gdb)


If I removed the code that transforms the
EXCEPTION_BREAKPOINT into a TARGET_SIGNAL_INT
I get this:

Program received signal SIGTRAP, Trace/breakpoint trap.
[Switching to Thread 2548.0xf1c]
0x7c901231 in ntdll!DbgUiConnectToDbg ()
   from /cygdrive/d/WINDOWS/system32/ntdll.dll
(top-gdb) c
Continuing.
[New Thread 2548.0xd10]

Program received signal SIGTRAP, Trace/breakpoint trap.
[Switching to Thread 2548.0xd10]
0x7c901231 in ntdll!DbgUiConnectToDbg ()
   from /cygdrive/d/WINDOWS/system32/ntdll.dll


I find it cleaner with signal SIGINT, 
but it's true that the other option is simpler
and not that different!

  Christopher, should I just remove the 
ctrl_break_sent variable and let 
GDB use SIGTRAP signal?
