title: Visual studio 2013 suddenly compiling really slow after BK4503 minor error appeared
body: <p>I've started to get this message while compiling</p>
  
  <p>BSCMAKE : warning BK4503: minor error in .SBR file 'C:\leisec-pcpcd.pcpcd\code\PCPCD\Debug\x64\build\Configuration.sbr' ignored</p>
  
  <p>I have not changed the Configuration.cpp file any time recently.
  I've tried to delete Configuration.sbr, or clean the solution and rebuild.
  This warning reappears.
  I don't mind the warning. What I do mind is that since this has appeared, compiling the solution
  has become really slow, even when just one cpp file has been altered.</p>
  
  <p>By the way, I've found posts about BK4503 in older versions of MSVS, but these haven't helped me.</p>
  
  <p>Also, this sudden slow compilation is only in debug mode.</p>
