When I use win32,the calling convention in glib and libusb is different

When I compile spicy with mingw32: In the libusb,the calling convention is pascal(stdcall):

#define API_EXPORTED LIBUSB_CALL DEFAULT_VISIBILITY

#if defined(_WIN32) || defined(__CYGWIN__) || defined(_WIN32_WCE)
#define LIBUSB_CALL WINAPI
#else
#define LIBUSB_CALL
#endif

#define WINAPI      FAR PASCAL
#define PASCAL          _pascal

But in the glib,the calling is cdecl:

// glib: gmem.h
typedef void            (*GDestroyNotify)       (gpointer       data);

#define g_clear_pointer(pp, destroy) \
  G_STMT_START {                                                               \
    G_STATIC_ASSERT (sizeof *(pp) == sizeof (gpointer));                       \
    /* Only one access, please */                                              \
    gpointer *_pp = (gpointer *) (pp);                                         \
    gpointer _p;                                                               \
    /* This assignment is needed to avoid a gcc warning */                     \
    GDestroyNotify _destroy = (GDestroyNotify) (destroy);                      \
                                                                               \
    _p = *_pp;                                                                 \
    if (_p) 								       \
      { 								       \
        *_pp = NULL;							       \
        _destroy (_p);                                                         \
      }                                                                        \
  } G_STMT_END
// spice-client: channel-usbredir.c
        g_clear_pointer(&priv->device, libusb_unref_device);

so the stack is broken
