Thanks for always trying out new systems. I think that support
for those systems in mingw-cross-env would be really great.

I agree that variant 1 is not the way to go.

Variant 3 might be an option if those files were package independent
(i.e. identical for each package). However, I don't think this is
the case here.

So I'm opting for variant 2, and to ping upstream about that issue.
Offering the patches to them might not make much sense. But a quick
note in their issue trackers would be very desirable, mentioning
that Autoconf version x.y works well and solves issues on those
platforms. The goal is to make them upgrade their Autoconf stuff
sooner than they would have without our notice. ;-)

And yes, those patches might become big, but I think we can afford
that, as it is a very simple solution that saves us from other
