When the solution is converted to Visual Studio 2010, the command line to invoke make_buildinfo changes from:
$(SolutionDir)make_buildinfo.exe" Debug "$(IntDir)\"
to
$(SolutionDir)make_buildinfo.exe" Debug "$(IntDir)"
If the final backslash is omitted, the backslash in IntDir will escape the quote, thus passing the quote in as part of the path name.

This solution is a hack-fix to that problem by skipping any trailing quote from the path name.  It works as long as we don't need any additional arguments to make_buildinfo.exe.  This will help all those sould that are going to run this project through the visual studio autoconverter and get the same error.
