The only people who have contributed amounts of code large enough for the
FSF to requires an assignment are David Miller (davem@redhat.com) and

David has.  I btw. cannot remember having seen any mail from you regarding
copyright assignments of GDB.

I don't know what you look at - ld.so fails to handle libraries which are
not linked to 0x5fffe000 ...
