Hi Magnus,

I think we need to understand more about why this stopped working before reenabling it. I also would like to know how this fixes things when according to the Github folk:

https://github.com/actions/virtual-environments/issues/3567#issuecomment-862908135

the issue is using VC instead of cygwin. If there is a misunderstanding about how the build works it would be good to clear that up and document it.

Thanks,
David
