/* machine.c, 27-03-1990, F. Meulenbroeks
 * usage: machine [machine name]
 *        chip [chip name]
 * where machine name or chip name are the same as the macros from 
 * <minix/config.h>
 * 
 * When executed without arguments this program returns either the machine name
 * or the chip name as found in <minix/config.h>
 * the chip name is returned if argv[0] ends on "chip". 
 * otherwise the machine name is returned
 *
 * when executed with an argument that argument is (case insensitive)
 * compared with the machine name, and depending on whether these match
 * or not 0 or 1 is returned as the exit code. In this case nothing is printed
