In general the Darwin ld is going to object to multiple definitions
of the same symbol layered on top of each other. This is a Mac-ism
brought over by popular insistence I'm told. Usually I see it
manifest as a warning rather than an error though...
In any case, you'll have to get rid of that definition of read()
in os_dep.o. (Note that libm.dylib is a symlink to libSystem.dylib,
which is Darwin equivalent of libc).
