Why not gnat Ada in gcc?

[Richard Kenner]

    Well, that sounds like the solution to the problem, then.  What you've
    got here is a case of people following the rules of the GPL, violating
    their NDA, and not having the NDA enforced against them.  So long as
    no-one enforces the NDA, what's the problem?

None if a company is going to assume that companies such as Intel won't
enforce their NDA!  However, most companies I know of would certainly assume
that Intel *would* enforce their agreement and would severely discipline any
employee that caused them to breach such an agreement.
