[Bug 21423] Visual C++ 2005 slow?

This bug is about cl.exe being slow when given an .rsp file with
lots of .cc files in it, as devenv does.  
(In that case, cl's startup time doesn't matter much,
since it only has to start once for that whole batch of files.)

See bug 21566 for cl.exe being slow to start up
(which matters when starting cl.exe once for each input file, as make does).
