Agreed. Anything that doesn't need to be implemented in the Basis (or
need direct compiler support) should be in its own library.

O.k. I thought it was being used on more; but it's just that ldl is
available through the standard lib on Cygwin, Darwin, and *BSD.

I don't see why. ldl only seems to provide the dl* functions, which
shouldn't be necessary for normal MLton compiles.

Well, proper use of any linker option requires -target-link-opt, if you
want to account for what may or may not be in the standard lib on
different machines.
