[Rivet] Python 3

[Andy Buckley]

Yep, the same happened for me when I tried today. Definitely needed a
proper fix... but boy was it more fiddly than expected. I won't bore
you with the details, but the m4 macro is patched and pushed, and I've
submitted the patch to the GNU autoconf macro maintainer... I was
originally hoping that someone else had already done it!

Cheers,
Andy
