[omniORB] omniEvents & cygwin

[Alex Tingle]

Thanks for trying the experimental omniEvents. I think I can fix your
compilation problems:

You don't have a constructor for ifstream from C style FILE. A
workaround (NOT a proper fix) is to change it from 
  ifstream persiststream(fileno(file));
to:
  fclose(file);
  ifstream persiststream(active);

This is the same problem that we see in GCC3. Look in README.gcc for a
fix. (Don't try to apply the patch it's not for v2.5.1 - just make the
change manually.)

Let me know how you get on.
