 // Win32 console output.

 // If a Win32 application is linked as a console application it has a normal
 // standard output and standard error. In this case normal printf works fine
 // for output. However, if the application is linked as a GUI application,
 // the process doesn't have a console, and therefore (debugging) output is lost.
 // This is the case if we are embedded in a windows program (like a browser).
 // In order to be able to get debug output in this case the the debugging
 // facility using OutputDebugString. This output goes to the active debugger
