    Library_Options_Table.Append (Libgnat);

    --  ?? The proper implementation for the following code is to
    --  add only the libraries that libgnat is using. This information
    --  is not readily available but we should be able to compute
    --  this from the ALI files.

    declare
       I : constant Natural := Object_Files.Last;
    begin
       --  Then adds back all libraries already on the command-line
       --  after libgnat to fulfill dependencies on OS libraries
       --  that may be used by the GNAT runtime. These are libraries
       --  added with a pragma Linker_Options in sources.

Not much help, I konw.
