From article <6396@ficc.uu.net>, by peter@ficc.uu.net (Peter da Silva):
/ The last time I looked at a stdio library there was a goto in _doprnt:
/ 
/ 	if you see a %
/ 	handle number.number stuff
/ 	see what the format is
/ 
/ 	switch(format) {
/ 		case 'd':
/ 			base = 10;
/ 			if(number < 0) {
/ 				sign = '-';
/ 				number = -number;
/ 			} else
/ 				sign = 0;
/ 			...
/ 			goto donum;
/ 		case 'u':
/ 			base = 10;
/ 			sign = 0;
/ 			...
/ 			goto donum;
/ 		case 'o':
/ 			base = 8;
/ 			sign = 0;
/ 			...
/ 			goto donum;
/ 		case 'x':
/ 			base = 16;
/ 			sign = 0;
/ 			...
/ 			goto donum;
/ 		donum:
/ 			format number with base, sign, etc.
/

	This must be really old code since in C, execution falls through
to the next case anywasy; in every case without the goto, it would hit
donum: anyways...(albiet after trying the rest of the case statements)
	A break usually replaces the goto in that type of code.
