[Development] The VS2008 WinCE errors

[Björn Breitmeyer]

Hi Thiago,

the internal error is a compiler bug. We don't exactly know whats necessary to 
trigger it. It happens more likely if there is more than one instance of the 
compiler running at the same time, or if a visual studio environment is 
opened. However some code pathes might be triggering this too.

The preprocessor output can be found here:

Best regards
