Well, since about august of last year or something.

The main difference between 64 bit dwarf2, and 32 bit dwarf2, is, of
course, the offset sizes.

The DWARF2.1 standard says that the cu header's initial length will tell
us whether we are dealing with 4 byte offsets or 8 byte offsets.

If you look at dwarf2read.c, you'll notice it handles offset sizes of both
4 and 8.
read_initial_length takes care of figuring out which offset size we have.
