Even at the time _FILE_OFFSET_BITS was introduced, I thought that it was a 
mistake for it to default to 32.  An understandable mistake, but a mistake 
nonetheless.  What a hassle it was to arrange for every application to #define 
_FILE_OFFSET_BITS to 64!

Can we avoid the mistake this time around, and have _TIME_BITS default to 64?
