/* This is a lowest-common-denominator program which should compile under
   the default cc on any system, no matter how primitive (even the SunOS
   one - note the use of 1970s-vintage octal escapes).  This is necessary
   because it's compiled before we can try and select a decent compiler via
   the makefile */
