create dontnet2 directive

[Tite Etoundi]

Hi,
   
  I'm facing a problem with the source revision-426164. In this source there 
something like:
  if (Environment.Version.Major >= 2)
  {
  #if dotnet2
  _objectFactory = new DelegateObjectFactory();
  #endif 
  }
  else
  {
  _objectFactory = new EmitObjectFactory();
  }
   
  for example. The execution goes into the first if but #if dotnet2 is never 
executed! I don't know I can create this directive. Also this directive is 
present in many files of iBatis. 
   
  How can I do to have the code included within the directive executed?
   
  Thanks!
