Er, um, resolv/res_libc.c in glibc 2.6.1 (and the very latest 2.8: the
file is unchanged) is only 152 lines long. There is no reference to
st_mtime anywhere under resolv/.
Are you sure that's stock?

Not in my universe :)

May I second that motion? Are you *sure* yours doesn't have any distro patches
applied? (Mine is straight from upstream CVS.)
This is something I can understand a distro vendor patching, and also
something I can see Ulrich rejecting, because banging stat()s on that
file with every name lookup seems expensive. (Doing it every minute or
so would be acceptable to me, but IIRC Ulrich turned that down as
well...)
