That's debatable.

Ironically, commercially-licenced versions of Motif are potentially
less of a problem, as the GPL provides an exception for "major
components ... of the operating system". On commercial Unices, Motif
is frequently part of the OS.

So, the issue primarily relates to OpenMotif (which is just a copy of
Motif distributed under the Open Group Public Licence; at a technical
level, OpenMotif is the same product as a commercial version of

Even there, it's only an issue insofar as Motif isn't considered
"standard" on platforms for which the OpenMotif licence applies.

No, it implies something compatible with IEEE 1295, i.e. Motif
(whether OpenMotif or a commercial version), or a clone thereof.

BTW, a version linked against OpenMotif (or even a commercial version)
should work with LessTif and vice-versa, although you might need to
add a symlink to cater for different major version numbers.
