Hmm... indeed I now see that liblcms2 is already linked into Emacs if we
use the Gtk GUI.  It's not linked if you use the Lucid GUI, OTOH.

That's one of the benefits.  The other is that you don't need to choose
at compile-time which libraries will be (and have to be) available at
run-time.

In Windows, we already do dynamic-loading of libraries such as gnutls,
so the issue is less serious, but in GNU/Linux it's always a hassle.

That calls for improving the module system, not circumventing it.
