Yes, you have to implement it, if you claim XPG4 conformance with XCU4
commands.  Note that you can claim XPG4 conformance with XPG3 commands,
or anything in between, as long as you describe the differences between
yours and either XCU4 or XPG3 Volume 1.  Get the branding information
(including the XPG4 Conformance Questionnaires) from X/Open for more details.

All of lint, cc, and dis are Development utilities.  You don't have
to implement them unless you want to claim the Development option.

You don't ever have to implement dis, since it's an optional part of the
Development option.  lint can often be implemented substantially
with an ANSI C compiler (or a modified ANSI C compiler).

Talk to X/Open for a full description of the required and optional
pieces of XCU4.
