 When I run ghc tests on windows using "make test", I see instances of the
 following:

 =====> T5442d(normal) 86 of 4093 [0, 1, 0]
 cd ./cabal && $MAKE -s --no-print-directory T5442d    </dev/null
 >T5442d.run.stdout 2>T5442d.run.stderr
 [Errno 1] Operation not permitted: './cabal/package.conf.T5442d.global'
 [Errno 90] Directory not empty: './cabal/package.conf.T5442d.global'
 [Errno 1] Operation not permitted: './cabal/package.conf.T5442d.user'
 [Errno 90] Directory not empty: './cabal/package.conf.T5442d.user'
 [Errno 1] Operation not permitted: './cabal/package.conf.T5442d.extra'

 Not sure if these are legitimately harmful, but something is going wrong.

 I am running ghc head on latest msys2. I also tried running the process as
 administrator to rule out permission issues due to handling symlinks.
