You want to use the syntax 128 days ago, 64 days ago, 32 days ago, 16 
days ago....  Also, in the absence of other information, you want to 
binary search.  Further, if you have lots of bugs to do this with, you 
want to cache cc1plus binaries, and use those first, before building 
anything.
If you build often, and have extra disk space, you can squirrel away 
cc1plus binaries into the cache to prime future searches.  Saving about 
one a week is good.
