Failure to compile

Summary

On Windows I get a compile error when trying to build GHC as at 795986aa. I am using the Hadrian/Stack approach.

Steps to reproduce

C:\Neil\ghc\2019-09-26\ghc>hadrian\build.stack.bat --configure tool-args -q --build-root=.hie-bios --flavour=ghc-in-ghci

Expected behavior

Print out some command line flags required to build GHC.

Environment

Windows 10. Stack 2.1.3.
