GHC.Compat

Compatibility layer for GHC. Supports GHC 7.4, 7.6, 7.8.

None of the ghc-server project should import from the GHC API directly, it should import via this layer. It exports everything from the GHC API that is needed. Ideally, only this module will use CPP, too.

Some symbols are not exported, usurped by compatible re-definitions. These compatibility wrappers are added on a case-by-case basis. Otherwise, everything is re-exported.

Each function has a type signature. Under each type signature lies an implementation dependent upon a specific major GHC version. When a new GHC version is added to the test builds, a new #if section will needed to be added for that specific version. If not, there will be a build error. This helps to ensure specific versions are dealt with.
