Also note that a minimal patch already exists which will ship in GHC 8.2: https://git.haskell.org/ghc.git/commitdiff/018ac7f4b2f7345e28d21fb1f99b44dbc79f6e85

It's 'just' a matter of packaging that up in a hotfix.

Hi,

when the Creators Update finally hits Windows 10 stable on April 11th (next week), every currently available GHC will be broken by it.

See [1] for the previous discussion, [2] and [3] for the tickets discussing this. From what I read on the GHC 8.2 status wiki page, there might be an interval of some weeks where it will not be possible to compile a Haskell program on any up-to-date Windows 10 installation.

I just wanted to raise awareness and offer myself to do guided grunt work (if there is any) to push out a hotfix/inplace patch release for GHC 8.0.2.

Greetings,
Sebastian
