- Fix debug info look-up (bug in translating the RVA of the debug directory). - Fix code for adding PE export table as debug info (crash with NULL passed to RtlImageDirectoryEntryToData). - Fix computation of non-relocatable ELF shared objects size. - Fix loading (while parsing the link map) of new non-relocatable ELF shared objects (no longer take account load-address of link-map). - Finished the AUTO_PUBLIC, NO_PUBLICS and PUBLICS_ONLY support for PE and ELF. - Cleaned up public symbol management (which should now properly work).
