To me that's really confusing. Especially as a windows user.

Haven't seen a '386 for over ten years.. Intel have standardised
to calling everything 'Pentium' pretty much since at least 2000.
imho 'win32' is a really confusing term. That implies that it won't
work on 64bit. When in fact it mostly will.

I would much prefer to see:
> Requires-Dist[windows]: pywin32 (>1.0)
> Requires-Dist[linux]: pyodbc (>1.0)
> Requires-Dist[mac]: pyodbc (>1.0)
> Requires-Dist[mac linux]: pyodbc (>1.0)
as platform markers. It doesn't require a big change to
the PEP. And it is actually simpler to implement I would

I think that means the same thing.
I really hope these guys can make it no more complex than
it needs to be. Then we will all be happy.
