This is needed for subsequent patches in clang so you can redirect errs and outs to OutputDebugString. The rationale for needing this is that debugging from Visual Studio will not allow you to capture stdout and stderr into its Output window but OutputDebugString is captured there. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This change (in clang...) will also be useful if you want to redirect compiler output you can just create your own raw_output_streams and pass to the compiler functions.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Together with MSVC style diagnostics this really helps in clang development where you can get from diagnostics directly to the code in question when debugging.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Please review and submit if good.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal>Erik<o:p></o:p></p></div></body></html>
