Started to notice that when I ran MSBuild at the command prompt it gathered and
reported 36 Warnings, but my Hudson CI machine was reporting only 16. Further
investigation found that the MSBuild waring parser was not picking up
SharePoint project validation warnings. I hand to change a few names here but
here are the sample warnings that were missed. Please update parser to catch
SharePoint packaging warnings.
