title: LLU bad suffix on number
body: <p>I have  a library that uses <code>LLU</code> as a suffix  for a uint64 literal.</p>
  
  <p>Visual studio 2010 (on windows7-64) complains about "bad suffix on number", patching the library to use <code>LL</code> works.
  Is there some preprocessor definition or properties check box I have to set to enable <code>LLU</code> ?</p>
  
  <p>ps anybody know which is the correct behaviour? I have always assumed that whatever VC++ did was the opposite of the standard - but things have improved recently.</p>
