  The check of which header files to include for the cputime() function does not properly check for MinGW on Windows, so it will include the headers from "#else".  This is in every source benchmark file.
  The following modification will address that problem.
  #if !defined (__sun) \
      && (defined (USG) || defined (__SVR4) || defined (_UNICOS) \
  	|| defined (__hpux) \
  	|| (defined(__WIN32__) && defined(__MINGW32__)))
  "__WIN32__" and "__MINGW32__" are defined for both "MinGW/msys" and "MinGW64/msys".  This is not an issue with Cygwin nor should the update affect it.
Without that change, what exactly happens?
