 From http://www.mail-archive.com/pld-cvs-commit@pld-linux.org/msg00229.html

 Fixes

   rtld.c: In function '_dl_start':

   dynamic-link.h:47: error: nested function 'elf_machine_rela_relative' declared but never defined

   dynamic-link.h:41: error: nested function 'elf_machine_rela' declared but never defined

 when compiling glibc-2.3.4 with gcc-4.0

 But see also

 http://sources.redhat.com/ml/libc-hacker/2005-02/msg00000.html

 and

 http://sources.redhat.com/ml/libc-hacker/2005-03/msg00008.html

 which seem to propose less radical fixes?

 Aha.  See also http://sources.redhat.com/bugzilla/show_bug.cgi?id=721
