imenu produces largely garbage:
(("*Rescan*" . -99) ("strerror" . #<marker at 1229 in util.h>)
("DEBUG_WARN" . #<marker at 1307 in util.h>) ("int" . #<marker at 5029
in util.h>) ("int" . #<marker at 5071 in util.h>) ("int" . #<marker at
5113 in util.h>) ("int" . #<marker at 5155 in util.h>) ("void"
. #<marker at 5197 in util.h>) ("member" . #<marker at 5235 in util.h>)
("merge_sort" . #<marker at 5462 in util.h>) ("heap_sort" . #<marker at
5532 in util.h>) ("mapl" . #<marker at 6121 in util.h>))
for the file <http://www.podval.org/~sds/data/util.h>
specifically,
typedef struct list_t {
struct list_t *next;
void *data;
} List_t;
is not represented.

trivially handled:
no id after struct => forward-sexp to skip over {} and get the next id.
