CVSROOT:	/cvs/uberbaum
Module name:	winsup
Changes by:	cgf@sources.redhat.com	2001-04-29 20:09:19

Modified files:
	cygwin         : ChangeLog exceptions.cc winsup.h 

Log message:
	* exceptions.cc (INIT_EXCEPTION_HANDLER): Eliminate.
	(init_exceptions): Just use init_exception_handler.
	(open_stackdumpfile): New function.
	(stack_info::first_time): Eliminate.
	(stack_info::init): Set up fields to avoid "first_time" consideration.
	(stack_info::walk): Remove "first_time" consideration.
	(stackdump): Change arguments to accept initial frame pointer and open stack
	file flag.
	(stack): Eliminate.
	(cygwin_stackdump): Use stackdump() rather than stack().
	(try_to_debug): Remove all synchronization logic.  Just keep looping in
	exception handler until debugger notices us.  Return 1 if successfully started
	debugger.
	(handle_exceptions): Just return if we know that we're debugging.  Reorganize
	to avoid creating a stackdump file if we are starting a debugger.  Return from
	exception handler if debugger started successfully.
	(sig_handle): Create a stackdump only if debugger wasn't started.
	* winsup.h (try_to_debug): Add an argument.
