// Precompiled header for Chromium project on Windows, not used by
// other build configurations. Using precompiled headers speeds the
// build up significantly, around 1/4th on VS 2010 on an HP Z600 with 12
// GB of memory.
//
// Numeric comments beside includes are the number of times they were
// included under src/chrome/browser on 2011/8/20, which was used as a
// baseline for deciding what to include in the PCH. Includes without
// a numeric comment are generally included at least 5 times. It may
// be possible to tweak the speed of the build by commenting out or
// removing some of the less frequently used headers.
