<p><font size=2 color=blue face=Arial><span style='font-size:10.0pt;font-family:
Arial;color:blue'>These macros never should have been committed, and absolutely
should be removed. They do nothing, and serve no purpose in the code
except to make it confusing. This is why patches must be self
contained. If the patch breaks something, then reverting it is the
correct solution.<o:p></o:p></span></font></p>
