|

lookup_transparent_type gets called when the the type in question
|

is a declaration, and we're trying to find its definition; but, for
|
||||
declarations, our type name deduction mechanism doesn't work.
|

There's nothing we can do to fix this in general, I think, in the
|

absence of debug information about namespaces (I've filed PR
|

gdb/1511 about this); until such debug information becomes more
|

prevalent, one heuristic which sometimes looks is to search for the

definition in namespaces containing the current namespace.

information becomes more widespread. (GCC 3.4 will be the first
