	cygwin         : ChangeLog cygheap.cc dll_init.cc dll_init.h 
	                 fhandler_termios.cc sync.cc 

Log message:
	* cygheap.cc (init_cygheap::close_ctty): Avoid closing console-cttys since they
	don't use archetypes and this will just result in double frees.
	* dll_init.cc (dll_list::protect): Define.
	(dll_list::alloc): Guard list access.
	(dll_list::detach): Ditto.
	* dll_init.h (dll_list::protect): Declare new muto.
	(dll_list::guard): Define/declare function to guard list access.
	* fhandler_termios.cc (fhandler_termios::sigflush): Avoid SEGV in pathological
	condition of get_ttyp() == NULL.
