Mostly because it requires us to compile complex and generally
unmaintained compatibility cruft into the kernel.

>2) Where is -lcompat used?  Are you talking of compat3x/compat4x?

No, this is not compat3x/compat4x.

A quick grep shows the string "-lcompat" at least the following
places.  Many of these ports will undoubtedly be able to autoconfigure
themselves to systems without libcompat.
