Some detail:

it appears instead of linking to the beginning of
the declaration, it links to the beginning of the
declarator (which can make a big difference in
multi-line declarations).

May be the AST (in its current form) isn't the best
device for this, as we track individual declarators
each in its own AST.Declaration, which thus carries
the line number the declarator appeared in, not the
start of the declaration.
If we used the PTree for this cross-referencing it
might work much better. Hmm...
