Errors from separated importc & bitsize pragmas

[cdunn2001]

I have this:

typedef struct {
    uint32_t read_rest:1, finished:1, dummy:29;
    int tid, beg, end, n_off, i;
    uint64_t curr_off;
    hts_pair64_t *off;
    hts_readrec_func *readrec;
    struct {
        int n, m;
        int *a;
    } bins;
} hts_itr_t;

I end up with stuff like this:

  hts_itr_t* {.importc: "hts_itr_t", header: "hts.h".} = object
    read_rest* {.importc: "read_rest".} {.bitsize: 1.}: uint32_t
    finished* {.importc: "finished".} {.bitsize: 1.}: uint32_t
    ...

The error is something like:

Error: ':' or '=' expected, but found '{.'

I fix this by merging the pragmas, e.g.

    read_rest* {.importc: "read_rest", bitsize: 1.}: uint32

Actually, I have the same problem with the union pragma, which also needs to be merged with the importc pragma but shows a slightly different error message.
