  * Find compiler version-specific output files automatically
  Also, clean up the way we find the output file. From the comment:
  
  # Finding the sample output.  The filename is of the form
  #
  #   <test>.stdout[-<compiler>][-<version>][-<wordsize>][-<platform>]
  #
  # and we pick the most specific version available.  The <version> is
  # the major version of the compiler (e.g. 6.8.2 would be "6.8").  For
  # more fine-grained control use if_compiler_lt().
  
  I'll update the wiki too.
