/***
*strcmp - compare two strings, returning less than, equal to, or greater than
*
*Purpose:
*	STRCMP compares two strings and returns an integer
*	to indicate whether the first is less than the second, the two are
*	equal, or whether the first is greater than the second.
*
*	Comparison is done byte by byte on an UNSIGNED basis, which is to
*	say that Null (0) is less than any other character (1-255).
*
*Entry:
*	const char * src - string for left-hand side of comparison
*	const char * dst - string for right-hand side of comparison
*
*Exit:
*	returns -1 if src <  dst
*	returns  0 if src == dst
*	returns +1 if src >  dst
*
*Exceptions:
