If it were a single patch, it would be no big deal.  Unfortunatly, it is 
an accumulating sequence of changes that will hit GDB/BINUTILS at some 
random point in the future (most (all?) patches that Nath. recently 
posted are being parked on a branch :-().

In the case of GDB, mega-jumbo breaking branch merges are not our style. 
  Nath. would effectively have to slow-mo re-play these changes into the 
src repository :-(
