Update.
1998-09-06 09:00 Ulrich Drepper <drepper@cygnus.com>
* version.h (VERSION): Bump to 2.0.96.
Rewrite runtime linker to be truly thread-safe. There is now no
global variable specifying the scope. We create all needed
scopes at the time the link maps are created.
* elf/Versions [GLIBC_2.1]: Add _dl_loaded and _dl_main_searchlist.
* elf/link.h: Add struct r_scope_elem and use this for l_searchlist,
l_symbolic_searchlist, l_scope, and l_local_scope elements in
struct link_map.
* elf/dl-close.c: Rewritten accordingly.
* elf/dl-deps.c: Likewise.
* elf/dl-error.c: Likewise.
* elf/dl-init.c: Likewise.
* elf/dl-load.c: Likewise.
