	cygwin         : ChangeLog cygheap.cc dlmalloc.c dtable.cc 
	                 dtable.h environ.cc exceptions.cc syscalls.cc 

Log message:
	* cygheap.cc (cfree): Remove malloc debugging probe.
	* dlmalloc.c (errprint): Remove abort() call which causes interesting error
	message printing to abort prematurely.
	* environ.cc: Sprinkle MALLOC_CHECKs liberally throughout.
	(_addenv): Allocate two empty elements at end of environ to
	(apparently) work around problems with some buggy applications.
	(winenv): Avoid calling alloca if no forced environment variable is present.
	
	* exceptions.cc (open_stackdumpfile): Don't print "Dumping stack trace to..."
	when running in a cygwin environment (i.e., the parent is a cygwin process).
	
	* dtable.cc (dtable::init_std_file_from_handle): Move device type detection
	code from build_fhandler here since it is only used by this function.
	(dtable::build_fhandler_from_name): New method.  Renamed from
	dtable::build_fhandler.
	(dtable::build_fhandler): Use build_fhandler_from_name.
	(cygwin_attach_handle_to_fd): Ditto.
	* syscalls.cc (_open): Ditto.
	(stat_worker): Ditto.
	* dtable.h (dtable::build_fhandler_from_name): Rename declaration from
	dtable::build_fhandler.
