Please describe the problem.

The change of resolver to LTS 19 (lts-19.16) still causes stack builds to fail on Windows with a plan construction problem. Pinning Win32 as Win32-2.11.1.0 in extra-deps as suggested by stack is not enough to resolve the issue -- one has to go further and pin Win32 as Win32-2.9.0.0 and do similarly with a few other GHC boot packages including Cabal. This setup then builds and tests just fine. I'm aware this needs to be probably addressed in the cabal file instead but as a user the patch below is my local fix for the issue.

What steps will reproduce the problem?

stack setup && stack build. Observe the following output:

Warning: C:\Projektit\git-annex.branchable.com\git-annex--BUILD-220730-b5dc04099\stack.yaml: Unrecognized field in ProjectAndConfigMonoid: explicit-setup-deps

Error: While constructing the build plan, the following exceptions were encountered:

    Win32-2.12.0.1 from stack configuration does not match (>=2.6.1.0 && <2.12.0.0)  (latest
                   matching version is 2.11.1.0)
needed since git-annex is a build target.

Some different approaches to resolving this:

  * Set 'allow-newer: true'
    in C:\hs-stack\config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps
    in C:\Projektit\git-annex.branchable.com\git-annex--BUILD-220730-b5dc04099\stack.yaml:

- Win32-2.11.1.0@sha256:f503acb4ea2e7da6433549d5ff7d0851da54f226df032b40ae51559c7914d62f,4387

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Git Annex is great. I use it several times a week with my multigigabyte backups, where it gives structure to my image-based backup routines, so you could say I'm a believer. :)
