As ax-gdb grows I am starting to wonder whether we could unify it with
eval.c somehow.

A static field may itself be of a type with static fields.  That doesn't
seem to be handled in this code... should it be?  And if so, be careful
about the case where a class refers to itself recursively via static
fields; we still have some printing bugs in this area :(
