Hi!

Vagrant Cascadian <vagrant <at> reproducible-builds.org> skribis:

Nice.  :-)

It could be avoided by changing just ‘configure’ (which this patch
already does actually), but it’s fine either way.

You can move that string to the previous line.

> +               (("2.2 2.0 1.8") "3.0 2.2 2.0 1.8"))))

Here you should either modify ‘config/guile.m4’, in which case
‘autoreconf’ will have to run (that should be automatic), or modify
‘configure’, in which case the dependency on Autotools is unnecessary.

The latter is a fine solution.

OK with a change along these lines!

Thanks,
Ludo’.
