  38 --  WARNING! This file is a default version that must be replaced for
  39 --  each platform by running gen-soccon.c which automatically generates
  40 --  the appropriate target specific values.
  41
  42 --  The values below were computed from a i686-pc-linux-gnu environment,

  44 --  to a new target is to replace this file appropriately.
  45
  46 --  This file is generated automatically, do not modify it by hand! Instead,
  47 --  make changes to gen-soccon.c and re-run it on each target.
