Hi Doug,

3.9 can be added

neither I, but we have a lot of code still around that need
to be moved to 3.X

and it is not the only one.

Only recently I succeded to build postgresql with Python 3.x
but the solution I found is very puzzling

As seems you have more experiance than me with Python,
can you look on it ?

All the ARCH packages seem affected. I am more or less patching
all the ARCH source packages to overcome the problem but it seems
to me more a workaround than a real understanding of why

    __declspec(dllexport)

is not working as expected for Python modules.
