That looks like a good suggestion: maybe make the test 'if (!emac)'
rather than explicitly comparing with zero.

Are you comfortable sending a patch to that effect? A patch generated by
git format-patch and sent with git send-email are usually the easiest.

If you have any difficulties, feel free to ping me off-list and I can
walk you through the process.

Regards,
Daniel
