	cygwin         : ChangeLog cygheap.cc dcrt0.cc exceptions.cc 
	                 fork.cc winsup.h 

Log message:
	* winsup.h (child_copy): Change prototype to match new functionality.
	* cygheap.cc (cygheap_fixup_in_child): Accommodate new child_copy arguments.
	* dcrt0.cc (dll_data_start): Move definition here from fork.
	(dll_data_end): Ditto.
	(dll_bss_start): Ditto.
	(dll_bss_end): Ditto.
	(handle_fork): New function.  Called when forked to deal with fork issues and
	copy data to this process from the parent.
	(dll_crt0_0): Call handle_fork when _PROC_FORK condition.
	(dll_crt0): Don't copy user_data when we've forked.  Don't zero first element
	of main_environment ever.
	(cygwin_dll_init): Ditto.
	* fork.cc (child_copy): Rename from fork_copy and change arguments so that each
	pair of things to copy gets its own descriptor.
	(frok::child): Remove fixup_mmaps_after_fork call here.  Move to handle_fork in
	dcrt0.cc.
	(frok::parent): Use child_copy rather than fork_copy and accommodate changes in
	parameters.
	* exceptions.cc (setup_handler): Delay test of whether we're locked until after
	GetThreadContext has been called since there are apparently cases where
	SuspendThread does not cause an immediate thread suspension.
