failed in gcc with target i686-pc-mingw32 again...

extern __attribute__((dllimport)) PyIntObject _Py_TrueStruct;
removing  __attribute__((dllimport)) or replacing __attribute__
((visibility("default"))) solves problem...

then we get more reduced testcase

typedef struct sfoo{
        int ob_refcnt;
} foo;
typedef struct sbar{
        int ob_refcnt;
} bar;
extern __attribute__((dllimport)) bar bar1;
foo* stub1(){
return (                                \
                \
        ((foo*)(((foo *) &bar1)))->ob_refcnt++), ((foo *) &bar1);
}
int main()
{
        foo* a=stub1();
        return a;
}
