Thanks for the link.

I added an extra bit of reporting in the latest version of cygport so it 
reports the wheel filename it's choking on:

> Installing python-cryptography-46.0.3-1.x86_64
> *** Info: installing 3.9

I'm kind of confused where the 'x' in 'x86_64' has gone here?

That seems kind of wrong to me -'86_64' isn't the name of anything.

But I thought anyhow, I should just change cygport to accept that, but 
currently, if we try to feed that wheel name into 'pip install', it 
fails with:

> ERROR: cryptography-46.0.3-cp39-abi3-cygwin_86_64.whl is not a supported wheel on this platform.

... so I'm not sure what's supposed to be happening here.
