Log Message:
In hat-trans, if a module has no export list, produce an export list
containing only the stuff that should be exported.  This avoids the
problem of overlapping definitions of internally-generated identifiers
(e.g. source positions) in a multi-module program.  A little bit of
a hack but should work.

(Also noticed that a default declaration should always be deleted by
the transformation).
