This is on powerpc-linux using readelf -a.
The "old" build, is CVS HEAD glibc as of 2005-11-17 using binutils
2.16.1.  The "new" build is CVS HEAD glibc from today, using binutils
CVS from 20051117.

old:

  2184: 000d81d0    44 FUNC    GLOBAL DEFAULT   10
getsockname@@GLIBC_2.0

With the patch I offered, it keeps these symbols as weak on ppc.  I had
tested it against ppc and x86_64.

x86_64 also had these symbols as weak before, but i386 did not:

   944: 000b90f0    57 FUNC    GLOBAL DEFAULT   11 bind@@GLIBC_2.0
(etc)

If you want bind, setsockopt, listen, and getsockname as weak, I'll redo
the patch against current CVS and resubmit.

Tks,
