We talked about this offline, and we decided that this was the right  
thing to do, even though it can't influence any results, save getting  
rid of the warning, so I checked it in.

I verified that the .o file before and after this change was byte  
identical, just to be sure that it couldn't be responsible for any  
change in behavior.

Jack, I put:

	* unwind-dw2-fde-darwin.c (getsectdatafromheader_64): Fix first
	arg to be struct mach_header_64* instead.

on it, let me know if you'd rather see something else.  Thanks.
