45 /* Provide a LINK_SPEC appropriate for Linux. Here we provide support
46 for the special GCC options -static and -shared, which allow us to
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
