It seems that System.Info.compilerVersion doesn't know the minor release number of ghc. This looks like a bug to me.

Last time I asked I was told it was by design. Similarly the __GLASGOW_HASKELL__ cpp macro does not tell you the patch level. I believe the rationale is that minor ghc versions are compatible (though because they're not really 100% in all cases they did add a patch level cpp macro). So you can try opening a ghc ticket, see if you can persuade them to reconsider. Duncan
