     3   rtld.c: In function '_dl_start':
     4   dynamic-link.h:47: error: nested function 'elf_machine_rela_relative' declared but never defined
     5   dynamic-link.h:41: error: nested function 'elf_machine_rela' declared but never defined
     6 when compiling glibc-2.3.4 with gcc-4.0

    10 and
    11 http://sources.redhat.com/ml/libc-hacker/2005-03/msg00008.html
    12 which seem to propose less radical fixes?

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