/* The following functions do nothing useful.  They are included
   simply as places to try setting breakpoints at.  They are
   explicitly "one-line functions" to verify that this case works
   (some versions of gcc have or have had problems with this).
  
   These functions are in a separate source file to prevent an
   optimizing compiler from inlining them and optimizing them away. */
