What's up with the comment....

/* Provide dummy functions to satisfy linkage for versions of the Darwin 
   tool-chain that that can't handle undefined weak refs at the link stage.
   ??? Define these dummy functions only when !HAVE_ELF_STYLE_WEAKREF. */

in libgcc/config/darwin-crt-tm.c? In particular, what versions of the Darwin
tool
chain were you using that required these dummy functions?
