In case you could not find it, here is the incantation:

  ld -dylib -all_load -flat_namespace -undefined suppress 
    /usr/local/lib/ocaml/libunix.a -ldylib1.o -o libunix.dylib

You can also link all these libraries directly in your dynamic linked
C library, without creating individual dlls (but this works only for
platforms such as darwin, where all code is position independent).
