	winsup/cygwin  : ChangeLog environ.cc exceptions.cc 
	                 fhandler_tty.cc sigproc.cc sigproc.h 
	                 syscalls.cc winsup.h 

Log message:
	* environ.cc: Eliminate oldstack CYGWIN option.
	* exceptions.cc (sfta): Eliminate obsolete function.
	(sgmb): Eliminate obsolete function.
	(class stack_info): Remove MS method for walking the stack.
	(stack_info::init): Just initialize required fields.
	(stack_info::brute_force): Rename to stack_info::walk.
	(handle_exceptions): Pass derived frame pointer to sig_send.
	(interrupt_setup): Clear saved frame pointer here.
	(interrupt_on_return): thestack is no longer a pointer.
	(call_handler): Accept a flag to indicate when a signal was sent from other
	than the main thread.  Use saved frame pointer for determining where to place
	signal handler call.
	(sig_handle): Accept "nonmain" argument.  Pass it to call_handler.
	* fhandler_tty.cc (fhandler_tty_common::__acquire_output_mutex): Change
	debugging output slightly.
	* (fhandler_tty_common::__release_output_mutex): Ditto.
	(fhandler_tty_slave::read): Fix a comment, remove a goto.
	* sigproc.cc (sig_send): Accept an optional frame pointer argument for use when
	suspending the main process.  sigcomplete_main is an autoreset event now.  Save
	frame pointer for non-main operation.
	(wait_sig): Make sigcomplete_main an autoreset event.  Eliminate NOSIGQUEUE.
	Pass rc to sig_handle to signify if this was a nonmain process.
	* sigproc.h: Reflect change to sig_send argument.
	* syscalls.cc (swab): Eliminate swab function since it is now available in
	newlib.
	* winsup.h (signal_dispatch): Change CONTEXT cx to DWORD ebp.
