any news here? thanks. |

very unlucky, to get no reply here. Any one can at least give me a work around? |

Yes, it appears that most people around have gone dormant. I just did a quick google on this issue. It appears there is no portable standard C++ way of specifying the alignment of a type. Can you provide details of why this is a problem and how it manifests? |

The compiler refuses to compile ;-) |
