Re: non-gcc linux?

[Tim Riker <Tim@Rikers.org>]

My understand of the argument for assigning all gcc copyright to the FSF
is that this make 'gcc' easier to defend. My example of an sgi-gcc shows
that sgi-gcc would have different criteria in a defense. This is solely
because both SGI and FSF would hold copyrights.

Now Marc Lehmann claims that this dual copyright code would be
"impossible" to defend. I merely pointed out that if that is truly the
case, gcc would also be indefensible because any GPL violator could
claim they took the source not from gcc, but from sgi-gcc which Marc
claims is indefensible.

I therefore assert that the fictitious sgi-gcc IS defensible and then by
conclusion that the current FSF position is not required to defend gcc
GPL. I am merely trying to assert what you stated as a given below:

In short the impact of adding code to gcc that is not copyright FSF is
minimal. Only the FSF copyrighted code would be defensible by the FSF.
Any other code GPL violations would be the responsibility of the
copyright owners to defend.

As before IANAL. ;-)
