--store-dir global flag doesn't seem to work

[Mistuke]

I'm trying to use the --store-dir global flag introduced in #4623 to change the location of the store. But no matter what I try it fails:

$ cabal --store-dir=/e/cabal-store new-test
Build profile: -w ghc-8.0.2 -O1

cabal.exe: ghc-pkg dump failed: dieVerbatim: user error (cabal.exe:
'E:\msys64\mingw64\bin\ghc-pkg.exe' exited with an error:
ghc-pkg.exe: C:cabal-store\ghc-8.0.2\package.db:
getDirectoryContents:findFirstFile: does not exist (The system cannot find the
path specified.)
)

Note the weird path it tries C:cabal-store\ghc-8.0.2\package.db which isn't valid due to the missing \ after C: but also isn't even the right drive. I wanted the store to be on E:\.

This is strange. I just tried cabal --store-dir=D:\\store new-build exe:cabal with cabal HEAD on Windows 10 and it worked as expected.

Edit: also cabal --store-dir=D:\\store new-test worked. And I see you are on ghc-8.0.2. I used ghc-8.2.1.

Edit 2: Even with cabal --store-dir=/d/store ...` it seems to work.

@Mistuke

--store-dir=/e/cabal-store new-test

Are you using Cygwin by any chance? What if you try --store-dir=e:/cabal-store new-test?

[Mistuke]

I'm using msys2 and same thing. I've tried every variation of paths Unix, mixed and windows. :(

Oddly enough it seems to work now, so I'll chalk this one up to local environment..
