It will cover all FSF contributions.

If config/ax_pthread.m4 is accepted by the config maintainers, I doubt
you'd need an assignment for that, since it's already licensed and
it's not actually your contribution.

That leaves a fairly small change to gold sources (not counting
auto-regenerated files) -- small enough that I don't think you need to
complete an assignment.

If  you do want to file a copyright assignment for future changes,
I'll forward you a copy of the form and instructions separately.

I've added config-patches to the conversation, so I'm hoping that was
sufficient to get that going. Once added in the GCC tree, I think one
can either wait for an automatic sync, or go ahead and submit a patch
to do the sync (but I'm not completely versed on how the shared
directories really operate).

That suggests to me that there shouldn't be a problem adding this new file.

Sounds good to me if others agree.

It's a convention that makes reviewing and applying patches easier for
us maintainers, but it's easy to forget to strip out those diffs.
