title: GHC 7.4 update breaks haskell98?
body: <p>I updated ghc today and my small program stopped working:</p>
  
  <p><a href="https://github.com/BrisFunctional/misere-oxo/blob/master/OXO/misere.hs">https://github.com/BrisFunctional/misere-oxo/blob/master/OXO/misere.hs</a></p>
  
  <p>GHC is now version 7.4.1-2 and from what I managed to understand it now defaults
  to  haskell2010 standard, instead of haskell98. (as I can see from the output of ghc-pkg list):</p>
  
  <pre><code>haskell2010-1.1.0.1
  (haskell98-2.0.0.1)
  </code></pre>
  
  <p>So I changed my "import List" to "import Data.List" which I thought was the only problem but now I get the following:</p>
  
  <pre><code> misere.hs:1:1: Not in scope: `System.Environment.withArgs'
  </code></pre>
  
  <p>where does that come from since I never even import System.Environment?
  Any hint?
  Thanks</p>
  
  <p>EDIT:
  I updated the version on github to reflect this error. and actually using Data.List ghc compiles the file perfectly, so it's runhaskell that generates this problem..</p>
