The dreaded windows path length issue

[Erik de Castro Lopo]

Hi all,

I'm now working for IOHK on the Cardano project. The Cardano code
base is large and we are hitting the dreaded windows path length
bug. We have already shortned build paths as much as possible
but are still hitting this

We're currently using ghc-8.0.2 but even ghc-8.2.2 has this
issue. A snippet of the logs in included below. 

I took the liberty of including Tamar on this since he is the known
Windows expert. Not having a local Window makes this really difficult
to debug.

Anyone have any solutions for this? I'm willing to backport patches
if needed.

I've managed to find a VirtualBox evaluation image on the Microsoft
site. Hopefully that will give me enough to debug this issue.

Cheers,
Erik
