When we do the port, Philippe Vouters and I, of libffi to OpenVMS we
(mostly Philippe) do the port for Alpha and I64.

In fact, we do the port for Python.

So you can build Python 3 on Alpha without any problem.

A few months ago I have asked if anyone is interested having a Python
3.10 on Alpha, no replies, as all customers who use Python on OpenVMS
are on I64, I only ld images for I64.

All the sources, Python 3.10 and libffi and others are on
https://foss.vmsgenerations.org/

So if you want a Python 3 on Alpha it's not very difficult to build it.

And Python 3.10 will be provided on X86-64, I have build some libraries
without any problem, the only expected one will be libffi.

The Python 3.10 port have the same VMS extension as the 2.7 version.
This is very important for customers who have large Python applications
on VMS.

Currently, the only limitation is that Python 3.10 expect some modern
CRTL so need VSI VMS version with latest CRTL patches. But I know
someone which is investigating is it can be backported to 8.4 HP version.
