          Issue ID: 22757
           Summary: importC:Error: forward reference to (*pRowSet).pChunk

The following reduced C code from sqlite fails to compile:


typedef struct RowSet RowSet;
struct RowSetChunk {
    struct RowSetChunk *pNextChunk;
};
struct RowSet {
    struct RowSetChunk *pChunk;
};
void foo(struct RowSet *pRowSet){
    struct RowSetChunk **ppPrevTree = &pRowSet->pChunk; // Error: forward
reference to `(*pRowSet).pChunk`
}

Oddly, if you remove the typedef it compiles without error, even though the
typedef is not used at all. If you move the typedef, it also compiles without
error.
