Darwin doesn't use ELF, and it doesn't use the GNU linker (at least,
not the mainline GNU linker--I don't really know what it uses).  I
have no idea whether they have done the same work to support common
symbols in shared libraries.

I don't believe that they use any part of GNU ld. They do use part of GNU as. It appears that parts of the dynamic linker are open source.

If you are curious, the open source parts are available for download from Apple, as part of the cctools package. http://www.opensource.apple.com/darwinsource/index.html I haven't tried looking at them myself. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
