45 | /* Provide a LINK_SPEC appropriate for Linux. Here we provide support | |

47 | link things in one of these three modes by applying the appropriate | |
48 | combinations of options at link-time. We like to support here for | |
49 | as many of the other GNU linker options as possible. But I don't | |
50 | have the time to search for those flags. I am sure how to add | |
51 | support for -soname shared_object_name. H.J. | |

53 | I took out %{v:%{!V:-V}}. It is too much :-(. They can use | |
