* Makefile.in (mingw-hdep.o, posix-hdep.o, remote-fileio.o): Update.

Browse Source 
* event-loop.c (call_async_signal_handler): New.
	* event-loop.h (call_async_signal_handler)
	(gdb_call_async_signal_handler): Declare.
	(mark_async_signal_handler): Add comments.
	* event-top.c (handle_sigint): Use gdb_call_async_signal_handler.
	* mingw-hdep.c (sigint_event, sigint_handler): New.
	(gdb_select): Use them.  Wait for the readline signal handler
	to finish.
	(gdb_call_async_signal_handler, _initialize_mingw_hdep): New functions.
	* posix-hdep.c (gdb_call_async_signal_handler): New function.
	* remote-fileio.c (sigint_fileio_token, async_remote_fileio_interrupt):
	New.
	(remote_fileio_ctrl_c_signal_handler): Use
	gdb_call_async_signal_handler.
	(initialize_remote_fileio): Initialize sigint_fileio_token.
	* remote.c (initialize_sigint_signal_handler, handle_remote_sigint): Do
	not initialize tokens here.
	(handle_remote_sigint_twice): Likewise.  Reinstall
	handle_remote_sigint.
	(async_remote_interrupt_twice): Just call interrupt_query.
	(cleanup_sigint_signal_handler): Do not delete tokens.
	(remote_interrupt, remote_interrupt_twice): Use
	gdb_call_async_signal_handler.
	(interrupt_query): Reinstall the default signal handler.
	(_initialize_remote): Initialize tokens here.
