This looks like a limitation in how typedefs are stored.  I'd guess that
if the C code were re-written as

struct foo { ... };

typedef struct foo foo_t;

then it might work in both cases there as well.

The solution may be that the C parser would need to identify a compound typedef
and (internally) split it into two individual TAGS covering the same space
in the buffer.  I think it is the function `semantic-expand-c-nonterminal'
in semantic 1.4.

Anyone want to give this a try?
