Compiling on Windows

[Neil Mitchell]

Hi,

At ICFP Simon Peyton Jones encouraged me to compile GHC on Windows. I
did so in the past about 5 years ago, and it was a painful experience.
To help improve the path for those who come after me, I kept a log
(which I'll share after I get a working build). My current state is
that I get an error while running make while building stage2:

Any idea how to overcome that? I note from the weekly update email
that there was an email on Windows last night, but a "./sync-all pull"
doesn't make it go away.

Thanks, Neil
