Hi!
I tried sending this a month ago, but it hasn't hit the mailing list
yet. I've removed the URL to the macports patch, perhaps that will
allow this to go through.
Original email:
Hi!
I'm looking at updating m4 in pkgsrc, and found another old patch.
pkgsrc comes from NetBSD, but it's been used on many platforms,
including old macOS releases. For that reason we've adapted (a
macports patch).
I'll attach the current version, can you please consider it for
inclusion?
Thanks,
Thomas

Use older regnames on MacOS X 10.4 "Tiger", taken from macports.
