Hmm, I'll have to look into that, although practically speaking I don't
think it's much of a concern.

No they wouldn't, no more than anyone installing unison has to install
ocaml.

While ocaml has the toplevel system for use as a script interpreter and
runtime system for bytecode interpretation, the primary practical use of
ocaml (on platforms which support it) is as a native code compiler.  On
these platforms, ocaml *programs* are generally native-compiled for much
better performance, and such use requires -devel packages.

This is particularly true on x86_64-cygwin, where we don't have flexdll
working yet (although upstream is making progress), which severely
limits the usefulness of bytecode interpretation.

inherit commands are intended to be at the top of the .cygport, preceded
only by variables that are required thereby (as indicated in the
manual).
