--- Package Ids that are wired in
-
--- Certain packages are "known" to the compiler, in that we know about certain
--- entities that reside in these packages, and the compiler needs to 
--- declare static Modules and Names that refer to these packages.  Hence
--- the wired-in packages can't include version numbers, since we don't want
--- to bake the version numbers of these packages into GHC.
---
--- So here's the plan.  Wired-in packages are still versioned as
--- normal in the packages database, and you can still have multiple
--- versions of them installed.  However, for each invocation of GHC,
--- only a single instance of each wired-in package will be recognised
--- (the desired one is selected via -package/-hide-package), and GHC
--- will use the unversioned PackageId below when referring to it,
--- including in .hi files and object file symbols.  Unselected
--- versions of wired-in packages will be ignored, as will any other
--- package that depends directly or indirectly on it (much as if you
--- had used -ignore-package).
