-
-[A28] {AJ} In a versioned libc a lot of symbols are now local that
-have been global symbols in previous versions. When defining a extern
-variable both in a user program and extern in the libc the links
-resolves this to only one reference - the one in the library. The
-problem is caused by either wrong program code or tools. In no case
-the global variables from libc should be used by any program. Since
-these reference are now local, you might see a message like:
-
-"msgfmt: error in loading shared libraries: : undefined symbol: _nl_domain_bindings"
-
-The only way to fix this is to recompile your program. Sorry, that's
-the price you might have to pay once for quite a number of advantages
-with symbol versioning.

-	  I get
-	    XXX: Symbol `_sys_errlist' has different size in shared object, consider re-linking
-	  Why?  What to do?''
-
-[A30] {UD} As the message says, relink the binary.  The problem is that
-very few symbols from the library can change in size and there is no way
-to avoid this.  _sys_errlist is a good example.  Occasionally there are
-new error numbers added to the kernel and this must be reflected at user
-level.
-
-But this does not mean all programs are doomed once such a change is
-necessary.  Such symbols should normally not be used at all.  There are
-mechanisms to avoid using them.  In the case of _sys_errlist, there is the
-strerror() function which should _always_ be used instead.  So the correct
-fix is to rewrite that part of the application.
-
-In some situations (especially when testing a new library release) it might
-be possible that such a symbol size change slipped in though it must not
-happen.  So in case of doubt report such a warning message as a problem.
+There might be some more problems left but 2.1.61/2.0.32 fixes some of
+the known ones.  See the BUGS file for other known problems.
